Hi,

If CapCut on Windows shows “Security Notice” or says the app is unsafe, it is caused by one of these:

• corrupted install files
• modified/cracked CapCut versions
• VPN/firewall/network issues
• Windows security blocking the app
• leftover files from older installs

Try these steps:

1. Uninstall CapCut completely
   • Settings → Apps → Installed Apps → CapCut → Uninstall
   • Then delete leftover folders:
     • C:\Users\YOURNAME\AppData\Local\CapCut
     • C:\Program Files\CapCut
   • Restart the PC.
2. Download only the official version
   • Use the official site: CapCut Desktop
   • Avoid cracked/modded versions — they commonly trigger this notice.
3. Run CapCut as Administrator
   • Right-click CapCut → “Run as administrator”
   • Users in our forum have mentioned that this can temporarily remove the warning.

4. Check Windows Security
   • Open Windows Security → Virus & threat protection
   • If CapCut was quarantined, restore it.
   • Also try temporarily disabling:
     • Controlled Folder Access
     • Smart App Control
5. Turn off VPN or try another network
   • CapCut can flag connections/security environments incorrectly.
   • Users have fixed it by switching networks or using a VPN temporarily.

6. Update Windows
   • Install pending Windows updates.
   • Restart afterward.
7. Clear CapCut cache
   • Delete:
     • %localappdata%\CapCut
   • Reopen the app.
8. If you dual-booted or changed BIOS settings
   • Re-enable:
     • Secure Boot
     • TPM
   • Some security notices appear after boot configuration changes.

Can you share the below details to help you further on this:

• the exact wording of the security notice
• a screenshot
• your Windows version

Thanks. I followed these steps. It STILL pops up, but, ONLY when I click "Text" and ONLY if Wi-Fi is on?! This is absolutely bizarre and so frustrating, please help!

If the popup only appears when:

• you click Text
• and Wi-Fi is ON

then the trigger is CapCut’s cloud text system, not the editor itself.

The “Text” panel in CapCut is heavily tied to online services now:

• cloud fonts
• AI text effects
• templates
• TikTok-linked assets
• moderation/security validation
• account entitlement checks for Pro features

So when you open “Text,” CapCut makes a live API call and that is what is tripping the “Security Notice.”

That’s why:

• offline mode works
• other editing tabs work
• only Text breaks
• reinstalling didn’t fix it

We can narrow it down to following causes:

1. a bad server-side account/session flag
2. a broken security validation rollout
3. or a corrupted cloud-sync/token state

We will recommend you try the following steps:

1. Force CapCut into local-only mode for Text assets

Open CapCut with Wi-Fi ON, then:

• Settings
• Disable:
  • “Auto sync”
  • “Cloud space”
  • “Smart recommendations”
  • “AI features”
  • “Auto download resources”

Then:

• Sign OUT completely
• Restart PC
• Open CapCut WITHOUT logging in
• Try Text again

If Text now works:
→ the issue is almost certainly account-auth related.

2. Test with a completely fresh account

This is the most important diagnostic step.

Create:

• a brand-new email login
• NOT TikTok login
• NOT existing Pro account

Then test:

• open project
• click Text

Results interpretation:

• Fresh account works = your main account is flagged/broken server-side
• Fresh account fails too = install/network issue

We have observed that users have reported TikTok-linked accounts specifically causing the security popup loop.

3. Block CapCut’s online text resource calls (advanced but effective)

Try:

Windows Firewall outbound block

Block:

• CapCut.exe
• CapCutBrowser.exe
• Bytedance helper services

BUT:

• allow basic startup internet temporarily
• then disable after launch

This can sometimes preserve local editing while preventing the security trigger.

4. Delete ONLY cloud/auth cache

Not just reinstall.

Delete these folders completely:

C:\Users\YOURNAME\AppData\Local\CapCut
C:\Users\YOURNAME\AppData\Roaming\CapCut
C:\Users\YOURNAME\AppData\Local\Bytedance

A lot of people miss the Bytedance auth cache.

5. Disable DNS filtering / AdGuard / Pi-hole / NextDNS

This is a common cause.

CapCut’s Text tab appears to depend on multiple telemetry/security domains.

If any are blocked:

• security challenge fails
• app interprets response as “unsafe environment”

Temporarily disable:

• AdGuard
• NextDNS
• Pi-hole
• antivirus HTTPS scanning
• Brave Shields
• VPN DNS filtering

Then test Text again.

6. Try mobile hotspot instead of home Wi-Fi

This is a very useful test.

If:

• hotspot works
• home Wi-Fi fails

then:

• your ISP DNS
• router filtering
• firewall
• or network reputation system

may be involved.

7. Use an older offline-friendly build

Recent builds appear much more cloud-dependent.

Other CapCut users have noticed that it works better with:

• late 2024 desktop versions
• versions before aggressive AI integration

BUT:

• disable auto-update immediately
• block updater executable afterward

Otherwise it silently re-updates and breaks again.

The main idea here is it happens only with Text and when being online.

That almost rules out:

• GPU problems
• corrupted projects
• Windows issues

and points directly at:

• cloud auth
• text asset validation
• or security telemetry.

It feels like CapCut developers have accidentally tied a core editing feature to an over-aggressive online security system.
