terminate services with task manager if you continue to crash, if is not windows, rage, steam, discord or gta v >close it.
also if you infested with rootkits, that may trigger EAC so try deep scanning with kaspersky and download Process Monitor from microsoft and check if there is any weird stuff going on.
some programs may not let you close them with task manager, open the system configuration window and go to services, check the hide windows services and turn anything that isnt window related off and restart.
if you still crash with EVERY POSSIBLE SERVICE CLOSED, consider updating bios to the latest version.
Remember, if you crash on rage but not in singleplayer or fivem is rage/eac related so dont waste your time changing graphic settings (unless pc overheating, had a friend that had bad ventilation on his pc and he WOULD ALWAYS CRASH AT THE VAULT WHILE DOING THE CASINO HEIST, try running msi afterburner or your mobo statistic tool to see if temps go above 70º, then yea lower game graphics.).
Reinstalling the 100 gb game isnt a good idea (if you believe that there is a corrupt file, verify the integrity of the game with steam or epic, downloading the whole game again will only waste your time, only that). Try playing other games with EAC and see if they crash too (I play war thunder and squad and those game use EAC and i wasnt crashing on those so the problem was indeed rage/EAC).
And make sure you dont have mods in your game folder, asi files or folders that dont belong there, disable also enb and reshades.
disable discord overlay and steam global overlay (settings > in game)
disable all your anti virus before lauching rage.
