I can understand that UVI Workstation, and UVI Falcon and Cubase 11 (and cubase 10, and 9) have a long and rocky history.
However, as of today, REtrologue 3 which had been working fine, the VST3 version at
C:\Program Files\Common Files\VST3\Steinberg\Retrologue is causing a memory out of bounds (access violation or windows security policy violation, accessing memory outside its accepted area) access, which is causing Cubase 11 pro to crash at startup.
Cubase 11.0.41 pro
UVI Falcon latest (as of feb 2022) installed then removed again.
Windows 10 version 21H2 19044.1566
Retrologue termination is weird, and does not generate a dump file that can be analyzed, but the other one did generate a simple A/V and a crash dump (for falcon)
These files just started crashing cubase and I wonder if a recent windows update may have changed some API that is breaking a variety of plugins.
