i had this exact problem on windows 10, except i did end up deleting and re installing. however now i cannot log into my account at all on bedrock and when opening the launcher i have to re sign in every time even if i have signed in already. i have made a longer report saying exactly what happened .
i had this same issue, my launcher for bedrock wasnt updating so i deleted it. and reinstalled hoping it would automatically install to newest version, however when i got it again and tried logging into bedrock it said error code drowned. i have a childs account im pretty sure (17). i can log into the launcher fine but it doesnt keep me logged in and makes me re login ever time its opened and i cannot at all log into bedrock - i spent almost 4 hours trying all different things suggested on the internet and when it says learn more i followed instructions with it still not workinmg.
