@FLEARAR Here's a few things you can try/make sure of:
running pluto in virtual machines (parallels desktop, vmware, ...) doesn't work in case you're trying to do that
try closing all programs that are running in the background (especially steam, msi afterburner and rivatuner if you have them)
try excluding pluto from scanning in your av software: https://plutonium.pw/docs/antivirus/#how-do-i-fix-this-windows-defender
update your graphics drivers
if you have a vr headset plugged in unplug it
if you use an avermedia capture card uninstall it's drivers
repair your game files (https://plutonium.pw/docs/repair/)
verify the integrity of your system files:
open the start menu and search for "cmd"
run cmd as admin
execute the following command
dism /online /cleanup-image /restorehealth
restart your pc
