[MU4 Issue] Unable to run MU if VST plugin has a problems on start on Linux Mint

[DmitryArefiev]

To Reproduce

1. Install Linux Mint 20.2 Xfce Edition (from linuxmint.com)
2. Install VSTi from https://u-he.com/products/zebralette/
3. Try to run MU4

see what Terminal shows - terminal output.txt

Expected behavior
If there a problem to run VST instrument, MU should handle the exception and show a message about the problem
(MU should not be blocked to run)

Desktop (please complete the following information):

• OS: Linux Mint 20.2 Xfce Edition installed on Win laptop

Additional context
Regarding VST problem on that machine, I need some time to investigate why it's not running, maybe some additional packages are not installed

@DmitryArefiev - does this issue still persist?

@Tantacrul It's blocked for testing now #11550.. I would like to recheck the current issue when VST will be available on Linux

So how will you use Zebralette without a GUI if this gets fixed?
This happens with lots of Linux VST's, and not only those from u-he.
But they are all unusable anyway since no gui in MS4.0. So why bother.

@diedeno Yes, agree. The VST feature in Linux builds will be blocked for now - #11689
