Hey,
This occurred once yesterday on a project we’re working on. When starting the patch, vvvv (7.0-0361
) would show the splash screen and at some point silently crash. Starting the project again works. Found the following in Windows’ Event Log:
Error
Application: vvvv.exe
CoreCLR Version: 8.0.1525.16413
.NET Version: 8.0.15
Description: The process was terminated due to an unhandled exception.
Exception Info: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Can share the project privately if that helps debugging!
Thanks!
