Minecraft crashes when im on offline after sign in in 1.16.2

Minecraft crashes when I load it in offline after i sign in . it does not crash when im online. And also it does not crash if i didnt sign in and load in offline . i think it is to do with some New sign in ui changes in new 1.16.2 hotfix and minecraft didnt crash like that . and i just deleted some files in the log of the com.mojang folder and it does not crashes but it start newly and i have to sign in every time i want to play online and delete the file every time i want to play offline and it is so annoying.

So dear devolopers please do fix this !(it only happens in this hotfix and it doesn't crashes previously)
