S3 making my controllers tweak

why is it that on splatoon and ONLY SPLATOON 3 my switch controllers will fucking disconnect and i can’t FUCKING use them until idk HOW LONG it’s only on S3 also i can exit out the game and they’ll work fine??

i’m SUPER pissed right now because this happen when i was playing FUCKING RAINMAKER AND I LOST BOTH MATCHES. i feel so bad for my teammates and my shit gameplay i can’t play with my controllers off like they need to be ON the switch, idk why that’s just how i play??? does this happen to ANYBODY ELSE?? OR IS IT JUST ME?!
