Faulty SDL Trados Studio 2021 SR1 16.1.4.4184

Hi,

I've been working with Studio 2021 for a while now without any problems but since the last update 16.1.4.4184, I've been encountering several annoying problems.

1- Occasionally, Studio shuts down unexpectedly.

2- Since last week, the error message KEY ALREADY EXISTS Name of parameter: Key pops up on and off when opening projects (issue not related to personal plugins stored in the AppStore because I don't have any).

3- I cannot get rid of the notification Connection error  "No Internet connection".

My configuration and parameters remain unchanged.

I cannot work properly and it's very annoying.

Has anyone any tips to solve these problems?

Thank you!

Sophie.
