No, plugin is started/invoked at MB startup/clicking on plugin menu item, not on opening all plugin prefs or just openening Tagging Tools menu. I'm not sure what could I log in this situation.
Ah, you are right. Now it's even crashing a few seconds after the Musicbee start,
without me doing a thing.
This is the header of the Microsoft error message that pops up.

I googled that clr.dll and it could be a problem with my .net framework installation.
I don't know if this is the case, since everything else works normally.
