Can you test if #5902 is fixing this issue ?
I am not using this module anymore (neither do I use gnome).
Is this a HM-related problem or a megasync packaging issue ?

Just tested it and yes, it fixes the issue completely.

I'd say it was HM issue, since installing the package via configuration and adding it to startup applications in Tweaks worked fine..

Fixed by #5902 (you may now close this issue).
