Attempting to initialize the following effect failed

After downloading the latest version (3.1.2), my RX7 effects no longer initialize… can’t even open the program. I’ve uninstalled and reinstalled with the same result. I run Windows 10

The message : Attempting to initialize the following effect failed
In this case, any RX7 effect

Thoughts ?
