Hello AlexCKY,
thank you for posting on the Microsoft Community Forums.
If you had Windows File History or System Restore enabled, you might be able to recover previous versions of your files or the entire system state. Check if you can revert to a state before the accidental deletion.
If that do not help, you can consider seeking help from professional data recovery services. They may have specialized tools to recover data from encrypted drives.
Best regards,
Lei
