Is there a way to reset CapCut's effects if they are causing persistent errors?

There isn't a direct 'reset effects' button in CapCut. However, you can often resolve persistent effect errors by clearing the app's cache (if the option is available in your device's app settings), uninstalling and reinstalling CapCut (be sure to back up your projects first), or by ensuring all effect packs are updated to their latest versions.
