Halion Validation fails

I’m using Halion Sonic 7.0.10. I have both Cubase 12.0.7 and Dorico 4.3.31 installed on Windows 10.
They both run fine, which would suggest that my iLok & licenses are working. But in Vienna Ensemble Pro (7.3.3388) when I reset and rescan my VSTs, I get:

“(VST3) HALion Sonic: plug-in failed validation and has been disabled.”:

I’ve tried reinstalling the HALion Sonic instrument in Steinberg Download Manager and that didn’t help.

Help help! Thanks!
