Crashes when trying to login to Microsoft account. Webpage says that i can close the webpage after which an enormous error message appears on my minecraft screen:

Greetings,

Its on 1.12.2 Forge btw, forgot to mention that

This is a bug from Mojang changing the certs in the java version they use. I still haven't backported the fix from 1.12. I'll try to get it as soon as I can

Could you update to the most recent version and let me know if the issue is fixed?
