: If a specific program is causing the error, try uninstalling and then reinstalling the software. This can help if the DLL was accidentally deleted during an uninstallation process or if the installation was corrupted.

Open your antivirus software (e.g., Windows Defender) and check the "Quarantine" or "Protection History" section. If fcore.dll is listed, restore it and add the Filmora installation folder to your Exclusion List to prevent it from being deleted again.
