IMAP Inbox keeps disappearing from the list of folders
Ever since an upgrade in our internal systems to a newer version of dovecot, my Inbox folder in Evolution keeps disappearing. The rest of the folders do not disappear, but the Inbox does. To recover it, I have to open the dialog to manage subscriptions. Sometimes, the folder just appears immediately after opening the dialog. Sometimes the Inbox folder appears subscribed and I have to unsubscribe and subscribe to make it appear again and, sometimes, it appears already unsubscribed and I have to subscribe again.
Additionally, in the subscription management dialog, the Inbox has sometimes a long list of inexisting "NBOX" subfolders.
In any case, after re-subscribing and having the folder back, it may disappear again in a matter of seconds or minutes.
I believe the dovecot version is dovecot (1:2.3.4.1-5+deb10u7) from Debian Buster, but I would have to confirm.

I've followed the instructions at:
https://wiki.gnome.org/Apps/Evolution/Debugging
And run:
$ CAMEL_DEBUG=imapx:io evolution >& logfile
I'm included here the truncated and redacted logfile just before the Inbox disappears. I cannot include the whole file due to confidenciality reasons but, if you need it, I could hand it privately.
