Recurrent problems Trados Studio 2021

Hello,

I am experiencing some troubles with Trados Studio 2021:

1.- Start:

At start Studio says, from time to time, that it was unable to delete a plugin. It happens once then no. 

What could be the cause and foremost the solution?

2.- MT Enhanced plugin:

The plugin works perfectly with Google, but not with Microsoft. I have to reenter my credentials that I have renewed (thinking it would solve the problem).

It is a strange behavior since there is no problem with Google.

3.-Termbases in local network:

I use my termbases from a local network hard drive. Every time I open Trados Studio I have to set the path for the termbase i am willing to use.

Is it the normal behavior?

I know that it does not work with TM, but I could not find anything for termbases.

Here is what Trados says:

4.- Third party plugin:

I am using Wordlight, downloaded from the AppStore. Trados warns me that the plugin was not validated by SDL and ask if I want to use it.

That a good warning in essence, but we would somehow expect that plugins offered via the AppStore are verified.

This process delays Trados Studio start up, and implies that we stay in front of the computer to validate the prompt.

Is there a way to validate the plugin for ever, with a case to click where it would say "Don't show this again?

Here is my log file:

I have Trados Studio latest version.

Thank you in advance for your inputs.

Best regards,

Eleana
