Can't log on MSN with Crosstalk

Hiii!!! So my best friend and I are moving to Crosstalk because we aren’t satisfied with Escargot chat and what happened with them

We have our email. I choose WLM cus it’s patched but when I put the email I choose (wafflechuu@proton.me). It just don’t work… We don’t know what to do, we wanted to join the Discord server to get help but it expired :sob::sob::sob:

Any help would be appreciated. We tried since hours and we don’t know what to do, thank you ^^
