This just stared to apear when I open my ungoing project.
Never heard of REV-X-VST 3 plugin.
Googled it never seen this plugin before.
I have no info of this in eLicenseControllCenter
When this appears Cubase 10.5 hangs.
I manage to get the project open once and checked I do not use this plugin on any tracks but then another Message popped up
Same massage but another plugin CLEAN VST or something never heard of that either and cubase froze.
