Problems with plug-ins uninstall process in Studio 2021

Hi

In Studio 2021 the process of installing/uninstalling plug-ins from  the Appstore has been greatly simplified.

Unfortunately, it does not seem to work flawlessly at all times.

Often, after adding a new plug-in, I get this error message after restarting Studio to install the plug-in:

After restarting Studio, not only the new plugin does not work, but other previously installed plug-ins are not active anymore. Although they do show up in the list of installed plugins, their icons do not show in the ribbon section 'Add-ins'.

The problem can be solved by uninstalling and reinstalling the plug-in once more or by logging of the window user.

This error mainly occurred with the plug-in "Wordbird", but I am not sure it is only related to this plug-in.

Anyone else facing similar problems?
