Hello, I just got this error message when starting ACAD 2020 LT. Any ideas what it could mean?

Hi,

i suggest to check if any updates needed for your AutoCAD ?

And how can I do this if I can't start ACAD and Autodesk Desktop App don't load anything for some reason.

So many possible solutions there . Reinstalling AutoCAD worked for me. Thanks.
