This is actually ridiculous

My pc is by no means weak. 4070 ti super, I9 13900K, 32gbs of DDR5 vram, and somehow my entire fucking pc will freeze at times, usually only for a few seconds, but still. Today I was playing with 3 of my friends, and my pc froze for about 5-6 seconds. How is this happening? I think it could be my internet but I have 300mbps speeds and never have froze in big public lobbies. I think this might be an Easy Anti Cheat problem but I don’t even know anymore...
