Trados Studio 2021 SR2 - slow and can't uninstall

Hi all,

Suddenly, my Trados Studio 2021 SR2 is very slow. I work in Windows 10 on a PC.

I've read previous topics where Studio slowed down due to slow server or software that connects it to the server.

However my Studio isn't connected to any server, my TMs are on my local computer. Confirming a segment and moving to the next one takes about 10 seconds with the message "Generating Preview" at the bottom bar being displayed.

I haven't changed anything in my way to work, and I tried deactivating my antivirus as well.

I've reset Trados to its default state as described here:

I wanted to try this solution:

Unfortunately, I get the following error when I try to uninstall the software: "Setup detected a different version of this product already installed. If you wish to remove or repair that version, you must use that version's installer."

Does someone have another idea? Any suggestion?

Thanks in advance for your time.
