Cubase 10.5.20 - Crashing on Project Load

I have several projects will not load in Cubase 10.5. It appears the issue is related to projects with the XLN RC-20 Retro Color plugin used. Projects open fine in “safe” mode (no third party plugins), but otherwise will crash Cubase while loading project MixConsole.

Cubase 10.5.20
Macbook Pro 16" (2019 - i9 2.3GHz)
Catalina 10.15.5

Crash log is attached
Cubase 10.5_2020-07-30-211525_Chads-MacBook-Pro.crash (164 KB)

Hi,

The crash is completely in the plug-in. Please get in contact with the plug-in manufacturer.
