Match making problems

I can’t come to any match on my account. I have tried switching account and it works perfectly. My question is, why is it only my account. I’ve tried everything in the book to fix the problem. TC my user name is “kzful” you need to go on my account try finding a match. I keep getting error code (0x80190f4) I searched up the code doesn’t exist. So I’m thinking the recent update messed up my account. If anyone else is having this problem message me on my profile kzful. Thanks
