Overwatch keeps crashing

I play on a Switch 1 and every since the second week of Chapter 1, I keep getting sent back to the login screen and see the same two messages. “ DISCONNECTED: Lost Connection To Game Server (LC-202) and then “LOGIN ERROR: There Was A Problem While Trying To Authenticate With Blizzard. please Try Again Later. (BC-123)” And even though I am not willingly leaving games, I still get suspended for 2 hours. I cannot afford to buy a different console right now. I have plenty of storage and I have even switch the Nintendo account attached to my Blizzard account. Someone please help me.
