Plugin class not found if 2 extra plugins added

I want to report a problem with a client:

So if we move two Einhugur plugins out, it builds:

But if we move them back in, it fails again.

Moving out a MBS Plugin doesn’t fix it. @Björn_Eiríksson has an idea?

Are you sure it is not just the famous Max DLL issue on Windows ? Since the 2 you moved just happened to be first ?

Note though I do see one error in both of the setups. TreeView hard depends on CoreClasses but I see no CoreClasses.

We now use dynamic runtime with DLL for all plugins except 5 or so.
So with MBS it should not be an issue.

And since Windows 10 with some newer build, the TLS limit was raised by Microsoft.
