My TM won’t update itself (different from previous posted problems)

Hi. In Trados Studio 2021 SR2 - 16.2.12.9338, my TM won’t update itself. Simple solutions just don’t work (ticking the box "update" for the TM in the Project parameters; also ticking the box Update TM after manual confirmation of segments in the Options>Editor>Automation). If I revert to Trados Studio 2019, then my TM does update itself. What am I missing? And where?
