I am facing the same issue and am unable to access the build. I have also updated the FAB plugin, but it is still not functioning. Please share the output log.

Thank you so much.
You are a real hero.
I checked yesterday to see if there was a new version, but didn’t find anything, it could also be because it’s very confusing, I was about to give up today but I checked again and now there was an update available. I updated and it works again, thanks! :smiley:
