VST Problem with Cubase Pro 10.5.12

I updated from Cubase Pro 10.0.50 to 10.5.12, and now Cubase can’t find 3 of my VSTs. I did a re-scan of my plugins, but no go.

So I rolled back to 10.0.50, and everything works.

Then I updated again, and the problem has returned.

So now I’m back on 10.0.50, and again everything works.

Has anyone else experienced this problem?


Make sure the plug-ins are up to date, please. What plug-ins are these, please?
