For the UDON bugs, i won’t be able to help, sorry, bug got a few links for bug reports
I’d say reporting is always best in the wait of a fix. Maybe add the sdk3 or vcc tag to the post so they could see it.
I know it’s not easy as they receive bug reports from many places, there is also their project Github page at Issues · vrchat-community/creator-companion · GitHub
And there is also the main feedback page from vrchat dedicated to the project at Creator Companion | VRChat
Finally, bug that’s an opinionated solution and that’s not endorced by VRChat, you may try to use the ALCOM Project, it’s a VCC Alternative developped by the community ALCOM: a crossplatform fast open-source unofficial Creator Companion alternative
