open Launcher as a Administrator. Right click on laucher > Run/open as administrator

wont work...also even if dont do this it automatically run as admin idk why

I'm sure someone made an issue about this error about elevation. IDK If a solution is put up but, try basics.
Clean up ur PC with fgunz files ( uninstall n delete everything) then install fresh. Or download it onto USB then try run it. Also learn about antivirus affecting you to run fgunz.

Did you try to google that exact error code?
Also, did you check if your Anti-Virus could be blocking the launcher?

/REQUEST LOCK
