Unexpected exception when initializing view Part Fragment Matches I can't fix this issue

Hi folks,

I've got the above error message when I tried opening a project that I had been working with not  problems.

I tired the solutions posted in this community, but I still have the same problem.

What I did:

Reset the Studio Trados 2019 via Control Panel,

Put %temp% in the search field via "Windows" + "R"

What should I do further to solve this issue?

Please help me.

Thank you.
