Hi
When using Cubase 10.5.0 and Synchron player (tried versions 1702 and 1744), if you create a new project within Cubase 10.5.0 and try to use Synhcron player, the moment you press a key, CUBASE will crash.
However, if you use Cubase 10.0.5 to create the project, it will work fine in 10.0.5. Furthermore, if you load the project made in 10.0.5 into Cubase 10.5.0, this also will work with out crashes.
Therefore, it would appear to be an issue between Synchron player and cubase 10.5.0. The work around is to create a template in 10.0.5 and then load that into 10.5.0.
I have updated VSL support with this information.
I hope it helps anyone else who may have got stuck with this fault.

Note: I have only been able to test with the audio interface UR22 mk11 - this fault may be specific tothis audio interface.
