Are you testing Avalonia UI? I noticed in my Install Extensions, I had something called Internal\Avalonia UI, which I had enabled in TC x64. When I launched TC x32, I got the same error message as you, appearing.
I'm now not able to get Internal\Avalonia UI appearing, so it could have been a bug
There's also a folder called SmartBear\TestComplete 15\x64\Bin\Extensions\AvaloniaUI, which I'm assuming shouldn't be there!
The option may be enabled for you, and hence is causing the issue.
Hi,
Avalonia looks like to be some set of UI controls that SmartBear decided to migrate to for some reason - https://support.smartbear.com/testcomplete/docs/general-info/version-history/features-added-to-ver-15-78.html
Looks like either problem with controls themselves or the way they are used in TC...
