Apple Mail rules do not find the mailbox to be moved
I have the exact same issue as described here: Apple Mail rules do not find the mailbox … - Apple Community
I have rules set up in Mac Mail to move emails I receive to different mailboxes in my Google account. They will work, but if I quit and restart Mac Mail it 'forgets' the mailbox and gives the note in the rules window, under 'Perform the following action' 'Move Message' to mailbox: "Mailbox ... does not exist."
Mac mini, macOS 13.2
