Hi Papyzaru,
please do a fresh installation of HB in a new folder. Make sure all buddystore products are turned off (disable streaming).
Then try again please.
HBRelog and Studio60 stuff on your profile is causing the issues.
If HB questing works again you can try turning the products on again one after another to identify the one causing trouble.
Report this to the author then or wait for an update.
Kind regards
