Odd, and latest (387) the same? Is it only one specific patch or in general? Can you provide us with that patch?

3

Could it be that you use VL.Audio.VST? Because I have a note to myself here that it needs an update for latest preview to work.

4

Found better solution, no need to update VL.Audio.VST for now. Fixed in upcoming.

Ok, thanks. Patch compiles and opens again. I have some more stride related errors in the latest version, but they deserve their own bug report. Will do so later.
