Moving emails in Thunderbird to gmail (imap within Thunderbird)

my company has moved to Google Workspace and our old email provider is no longer operational. I'm trying to move emails within Thunderbird from one imap account to another (same email name). Frequently I get an error message when copying emails in bulk to my Gmail account, "Invalid Argument: unable to parse message".

I've done just about every suggestion I've found on the web via searching and looking within the Thunderbird support as well with no luck. Sadly, if I'm bulk moving emails and one of them throws the parse error the whole block fails to transfer. I then have to go through them 1 by 1 looking for the culprit(s). Uggh.

Any help is appreciated.

I'll check that solution there. Just a note though, this occurs when trying to move 1 or 20 emails. :(

Copying a small number from the local computer to an IMAP folder should work, but maybe not directly from one account's IMAP folder to another account's IMAP folder - if there are no other interfering factors.

It's very odd, I can find the specific emails that stop the process, skipping them avoids the issue. Nothing that I can see that makes them seem odd.
