Hello,
Unfortunately, i cannot reproduce your exact error, but i can reproduce a different one. When i try to add a mailbox names Modéles i get an error, so for some reasons character é is an issue:

but im able to create mailboxes with other characters:

can you please check your console while you try to name a folder Modéles and if you have an error there?

The folder was already there when I synced my Nextcloud Mail, so that's probably why I have this issue while Nextcloud Mail have these catchers.
