A unique fix involves moving the x360ce executable to a directory outside of "Program Files" (like the Desktop) to allow it to generate initial files without restrictive system permissions. Once the files are generated, they can be moved back to the game folder.
Mitigation & Fixes (ordered, try in sequence)
If your game is on Steam (or added as a non-Steam game), Steam’s built-in controller configuration tool is highly stable and does not require third-party injection tools. self protection failed error code 4 x360ce 2021
Because x360ce installs and manages system-level drivers, it cannot function properly under standard user permissions.
How to Fix "Self Protection Failed Error Code 4" in x360ce (2021/Updated) A unique fix involves moving the x360ce executable
Because x360ce interacts directly with system-level virtual drivers, running it with standard user privileges will often trigger Error Code 4. Right-click your file. Select Properties . Go to the Compatibility tab. Check the box for Run this program as an administrator . Click Apply and then OK . 2. Move x360ce to a Dedicated, Unrestricted Folder

Add Exceptions to Antivirus/Firewall Antivirus software often flags x360ce.
Security programs often mistake controller emulators for "trojans" or "hooks" because of how they inject code into games. Open Windows Security via the Start menu.
