Hi,
This is a quesiton and a solution at the same time :
I had a session stuck on “LOAD VST Connect” beeing grey. and VST connect would not start.
I tried repair connection but it didn’t work. Blank session would opent vst connect but not the session I was working on.
I found that :
deleting all vst connect reference in control room helped. I removed all in the INPUT tab, the control room. There was also a track in my session I removed.
Only then I did repair then the VST connect would load.
hope it helps if someone is stuck.
