I've been using GMTbot plugin for more than a year across multiple MB updates. With latest version it crashes.
I select the albums I want to tag, I launch GMTBot, as soon as I click Start Bot, MusicBee crashes.
It happens both in the Inbox and in the Music Explorer.
I have not changed any setting anywhere, neither MB, nor GMTBot, the only difference is the new release of MB.
I always update it with incremental installer, not full.
