CapCut app freezing

Hi,

It is surprising to notice especially since CapCut has been running smoothly for you before. Freezing and unresponsiveness on CapCut (especially the PC version) have become increasingly common lately, often after certain updates or due to system conflicts. Let us troubleshoot this step-by-step and get you back to smooth editing

1. Identify when it freezes

To narrow down the cause:

• Does CapCut freeze right after opening?

• Or only when editing or exporting?

• Or when you use AI tools / body effects / filters / keyframes / transitions?

Knowing this helps pinpoint whether it’s a system, GPU, or CapCut-specific feature issue.

2. Clear Cache and Reset App Data

CapCut stores a lot of preview and temp files that can cause freezing.

Try this:

1. Open CapCut PC.

2. Go to Settings → General → Clear Cache.
   (If you can’t open the app properly, skip to the next step.)

3. Also, navigate to this folder on your computer:

   C:\Users\<YourName>\AppData\Local\CapCut


   Delete or rename the Cache and Temp folders.

Then restart CapCut.

3. Update or Roll Back CapCut

Sometimes new updates introduce bugs:

• Go to our CapCut PC page and download the latest installer.
  Don’t just update from inside the app — reinstall from scratch.

• If the problem started after a recent update, try reinstalling an older version temporarily. 

4. Check your system resources

CapCut can hang if your PC runs out of memory or GPU power.

Do this:

• Open Task Manager → Performance tab while editing.

• Watch your CPU, GPU, Memory, and Disk usage.

• If memory is maxing out (80%+), CapCut can easily freeze.

Fix: Close browsers, Discord, or other apps using GPU/CPU.
If you use CapCut AI tools (like Auto Captions or Body Effects), those are GPU-heavy — make sure you’re on dedicated graphics, not integrated Intel.

5. Disable Hardware Acceleration

This one helps a lot of users as per the feedback we have received on this forum:

1. Open CapCut → Settings → Performance.

2. Turn off “Hardware Acceleration”.

3. Restart CapCut.

If your GPU drivers are older or mismatched, this can instantly stop the freezing.

6. Update GPU Drivers

Outdated GPU drivers are the #1 cause of CapCut freezing or lagging.

• NVIDIA: https://www.nvidia.com/download/index.aspx

• AMD: https://www.amd.com/en/support

• Intel: https://www.intel.com/content/www/us/en/download-center/home.html

After updating, reboot your computer.

7. Disable Third-Party Overlays

If you’re using screen recorders, Discord overlay, OBS, or NVIDIA ShadowPlay, they can interfere with CapCut’s rendering window.
Try closing them all and see if CapCut stabilizes.

8. Check for Corrupt Project Files

Sometimes a specific project causes crashes:

• Try opening a brand new empty project.
  If that one runs fine, the issue might be with the assets or cache in your current project.

• You can export key assets, delete cache, and reimport them to rebuild the timeline.

9. Reinstall CapCut Completely (Clean Install)

If nothing helps:

1. Uninstall CapCut.

2. Delete all related folders:

   C:\Users\<YourName>\AppData\Local\CapCut
C:\Program Files\CapCut


3. Restart your PC.

4. Download the latest version from the CapCut site, not the Microsoft Store.

10. CapCut Beta vs Stable

If you’re using CapCut Beta, switch to the Stable version or vice versa.
Sometimes the beta builds cause GPU freezes.

If you can tell us:

• Your CapCut version number (found in Settings → About),

• Your PC specs (CPU, RAM, GPU),

• And when it tends to freeze (opening / previewing / exporting / applying effect),

…we can give you an exact fix (for example, whether it’s a GPU conflict, cache bug, or database corruption).

In the meantime, checking CapCut’s log files is one of the best ways to figure out why it’s freezing, because they quietly record what’s going wrong behind the scenes (GPU crash, database corruption, failed effect load, etc.).

Here’s exactly how to find and interpret those logs

Step 1: Locate the CapCut Log Folder

CapCut stores its log files in your AppData directory.

On Windows:

1. Press Windows + R on your keyboard.

2. Type this and hit Enter:

   %AppData%\CapCut


3. If nothing shows up, try:

   C:\Users\<YourName>\AppData\Local\CapCut


   (replace <YourName> with your Windows username)

4. Inside that folder, look for subfolders like:

   logs


   crash


   debug


You might see files like:

capcut.log renderer.log ffmpeg.log crash_2025-10-20_18-32-45.log

Step 2: Identify the Most Recent Log

Sort the files by Date Modified (newest first).
Open the latest one with Notepad or Notepad++.

Step 3: Look for Common Error Signatures

Scroll to the bottom of the file — the last entries usually show what caused the freeze or crash.

Here are a few common patterns and what they mean:

Step 4: Check Windows Event Viewer

If the log doesn’t show much:

1. Press Windows + X → Event Viewer.

2. Go to Windows Logs → Application.

3. Find an Error with “CapCut.exe” as the source.

4. Right-click → Details → Copy the faulting module name (e.g., “gpu.dll”, “ffmpeg.dll”, etc.).

That tells us exactly which component crashed.

Step 5: Share the Relevant Lines for deeper fix

You can copy just the last 10–20 lines of your latest log file (not the entire thing).
Paste them here as a reply and we will read them and tell you what’s failing and how to fix it specifically.

Example of what to share:

[2025-10-20 17:42:31] INFO: Restarting renderer failed
