Crash when booting over Remote Desktop

[motzi]

Just tried to use Gamma on a remote PC via Windows Remote Desktop Connection.

Unfortunately Gamma 21.3 previews (tried 67 and 65) all crash on startup while processing “Generating C# - VL.Skia.HDE.vl”

This is the output of the Windows Event Viewer / Event logs / Application:

Faulting application name: vvvv.exe, version: 2021.3.0.67, time stamp: 0xea44c150

Stable Gamma 20.2.5 does not show this behaviour and runs fine via RDP.

It would be nice to have the possibility to use Gamma remotely via RDP for having classes for students with macs (VNC is not an option for authentication reasons).

this is the initial error from the .net Runtime:

However, if one starts Gamma locally and then connects via RDP, it runs fine

can you please try this with latest 2021.4 previews and report if the problem persists for you?

Works nicely now with the previews!
Thanks!
