Cant add new account

Im using Windows 11 and try to add my office 365 account to mailspring.
But when i do, I get this error “An unknown error has occurred (mailsync: 3765269347)”
I have tried to look here and google and cant seem to fix it…
Anyone know ?

Same issue on my side.
I tried adding my account with both Office365 and Sign in to Outlook option. Both aren’t working.
