If CapCut continues to crash or lag, uninstall the new app to check whether it’s interfering with CapCut’s performance.
Also, check for updates to CapCut and your operating system, as developers frequently release stability fixes.
Ensure CapCut has full permissions under Settings > Apps > CapCut > Permissions. You can also clear its cache (on Android) or reinstall the app on iOS to reset its internal data and improve performance.
