Did you upgrade exchangelib at that time? If not, then it’s a server issue. If you did, then please follow the advice above.

@Tre-Seibert Then I don't think it's the same issue. This one is apparently specific to exchangelib 5.1.0 and Ubuntu 20.04. Also, if you downgraded and still have the issue, then...
