Thanks for the help, but I fixed the problem, apparently the GX Corner had problems during the iniciation and the computer thought it was a huge task, so it kept repeating it endlessly, sorry for taking your time

@sgunhouse
the amount increases according to the number of free cpu, see hypothetically if I remove all apps it will consume a number almost equal to 100%

Three days ago i was playing Valorant with my friends so far so good but after a while i started to notice that the game was very lagged so i went to check the cpu and MY GOD, when i saw OperaGX it was consuming 100% of my CPU and the game ran at 17 FPS, then I closed the browser tabs to "unlag" the game, it didn't work, I tried to restart the computer, reinstall opera, saw if the processors were defective, I'm starting to think that can be a Bitcoin miner inside my computer and now I'm a few steps away from formatting, please if someone can help me I would be very grateful
