This morning, I updated to the latest version of Studio 2021. Following this, I was no longer able to open Trados. The icon would appear and then disappear immediately. I have since uninstalled and reinstalled twice to no avail. Thank you for your feedback
Hello NIcholas Crowther
Please try to reset Studio settings: https://gateway.sdl.com/apex/communityknowledge?articleName=000001417
Thank you,

Thank you very much. However, for the first two folders, it does not say what I should rename them to.
Hello again. No ProjectApi folder and when I try to rename the other folders, it says I cannot because another file in the folder is open even though everything is closed.
Any suggestions would be gratefully received. Studio 2021 has been great so far. First time I have had an issue after an update.
I have exactly the same issue. After I updated the plug in messages. It has stopped and I get the same message.
Hello Ramon Somoza
For Nicholas the issue was resolved by removing MT enhanced plugin from: C:\Users\%USERNAME%\AppData\Roaming\SDL\SDL Trados Studio\16\Plugins\Packages\
Please check if you have the same plugin in the same location. If not, try removing the other plugins, one by one, to se which one causes the issue. Then you can reinstall the other ones back.
Thank you,
Sorin
Good evening, I had the exact same issue and your solution worked for me, so thank you very much. 
Same here. Thank you, Sorin and Nicholas! Now, do you have any clue on how to use the MT Enhanced plug in again?
I opened a discussion on that here: https://community.rws.com/product-groups/trados-portfolio/rws-appstore/f/rws-appstore/42230/mt-enhanced-plug-in-does-not-work-and-studio-2021-sr2-won-t-open
