Hi,

CapCut on Windows can crash like that, and it is because of memory or GPU issues rather than just a random bug.

Quick fixes to attempt:

These solve a lot of CapCut crashes immediately:

• Restart CapCut + your PC
  (clears RAM leaks that build up during editing)
• Close heavy apps
  Chrome, Discord, games—anything eating RAM
• Run CapCut as Administrator
  Right-click → Run as admin
• Update CapCut
  Old versions crash more often

If it’s a Memory crash which is most likely cause

CapCut can be surprisingly heavy.

Check your RAM

• Press Ctrl + Shift + Esc → Performance tab
• If RAM usage is near 100% → that’s your crash

Fixes:

• Lower video resolution (edit in 720p instead of 1080p/4K)
• Remove heavy effects (blur, transitions, AI stuff)
• Split your project into smaller parts

GPU issues which is another very common cause

CapCut relies on your graphics card.

Try this:

• Update GPU drivers (NVIDIA / AMD / Intel)
• Or disable hardware acceleration:
  • CapCut Settings → Performance → turn OFF GPU acceleration

Clear CapCut cache (important)

Corrupted cache = constant crashing

Steps:

• Open CapCut
• Settings → Cache
• Click Clear cache

Last resort fixes to try if it’s still crashing

• Reinstall CapCut completely
• Install it on SSD (not HDD)
• Make sure your Windows is updated

If your PC has:

• 8GB RAM or less
• Integrated graphics only

CapCut will struggle, especially with effects or longer videos.

Quick workaround so you can finish your Telegram video

If you’re stuck right now:

• Export in chunks such as short clips
• Or temporarily switch to something lighter like:
  • Shotcut
  • DaVinci Resolve (heavier but more stable)

Can you post these details as a reply to this thread:

• Your RAM (e.g., 8GB / 16GB)
• GPU (if you know it)
• Video resolution you’re editing

We can study a little more as to why it’s crashing and give you a fix tailored to your setup.
