Compacting error after converting from ESR to Release

The other day I received an email from Mozilla suggesting I move from Thunderbird ESR to the Release version (Windows 11). I backed up my profile and installed Release 139.0.2. The following error is now popping up periodically in Thunderbird: "The folder 'Inbox on [myemailaddress]' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

I do not think this message is really related to disk space (there's plenty available) or file write privileges since nothing should have changed. I see that others have encountered this message where Thunderbird is trying to compact other folders. However, I did not see a solution applicable to my situation.

Thank you, in advance, for any insight in getting rid of this error.

There is currently a bug or two pending that causes this issue, but no solution yet. For now, you can disable automatic compact and/or set a higher compacting threshold value.
