"Object reference not set to an instance of an object" while analysing Word files with a TM

Here's a bug in Trados 2021 that I just found.

I have a small project containing three small Word files and a TM. When I create the project, the analysis works fine, but if for whatever reason I try to analyse it again (Batch Tasks > Analyse Files), I inevitably get the infamous "Object reference not set to an instance of an object" error and Trados gives me an analysis that is slightly different than the first one.

Whatever I do after that will always get me a wrong fuzzy matches wordcount.

Besides this, the translation workflow apparently works, as I was able to round-trip with pseudo-translate and I can create packages, it's just the analysis. Any idea? If any SDL engineer is interested, I can send the Word files and the TM through so he can replicate the error.
