When I used Restart Button for the first time, all my other add-ons were disabled.
Responding to developer:
It happened immediately after I pressed the restart button. Additionally, Thunderbird started not fully closing anymore. Some small part of it remained in the background (Process Explorer revealed that) and when I tried to launch it again, the system warned that "Thunderbird is still running". I am using Thunderbird 82 beta 1. Fortunately, I had backups of my profile and all is well again.
What makes you think Restart Button caused that?
The current beta versions (82.x) are extremely buggy, your problem has most likely nothing to do with the Restart Button. Thanks for responding.
