Impossibility to open a TMX file after downloading the 16.1.5.4270 version

Hello,

I have been using the SDL Trados Compatibility and Migration Power Pack app for a few months to work with TMX files. I have never had any problem until today and I am wondering if this is not linked to the Studio 2021 16.1.5.4270 version I downloaded last week. Now, when I try to use a TMX file, I get the following error message : "An exception has been raised by the target of an invocation." Could you possibly help me?
