Hello

I recently upgraded to Kubuntu 18.04 (64-b) from 17.10.
I'm an amateur musician, been using VST instruments through wine for years. Never had problems. Until now.
I was using Sforzando and other VST programs either as standalone or as a dll plugin (most frequently as dll). But since the upgrade, I am unable to use any of them. Sometimes I can use Festige to run VSTs but only about half of my Vst collection works. For the rest I only get errors. Same thing with Carla.
The reason why I post this here instead of the UbuntuStudio forum is because I think the issue is in Wine. I'm even trying to run winecfg and all I get is:
wine: Unhandled page fault on read access to 0x00000008 at address 0x7f0b1603d829 (thread 002a), starting debugger...
winedbg: Internal crash at 0x7f3b6831a829
Also it doesn't work from GUI.

If I try to run vsthost, I get:

Sometimes the x86 version would run, but now I get this:

So, should I reinstall wine? (and if so, what's the best to do it?) or is there a way to diagnose the issue? I'm using wine-2.0.1.
