Forum log in android

I am unable to log into a forum using chrome on an android device.  I had always been able to do this before the dec 2022 update but now I get "user name or password not correct" error messages.  I can log in on a windows laptop and if I access my profile settings I see the user name is a series of jibberish lettters and numbers (something like XFT56-TH45-CLKJ8TH-AE9TFD0 ) this is not the actual number but just a sample that shows you sort of  what it looks like.  I can not edit my user name in my settings profile so I assume that this is a result of user data being corrupted by the december 2022 update.  I can change my password in windows but this still generates the same can't log in message when I try to log in in android
