Long time Cubase user here (since SX3) and recently upgraded from 11 pro to 12 pro. Since upgrading, everything is working fine except Halion SE 7. Certain content sets will crash Cubase as soon as a note is played (the programs will load fine and instrument-specific controls appear but will then crash when playing any note). This happens with Halion Sonic 7 standalone app as well. This isn’t a random thing - it is repeatable every time. The factory HSS sets all load and play fine along with Hypnotic Dance, but others such as Verve, Novel Piano, and others I have been using successfully for years are now crashing every time. Anybody else experience something similar to this? Could it be a compatibility issue with some content sets or perhaps a bug?
I tried reaching out to support, but they refused to look into the matter since I am on a non-Ryzen chip still, but other than that the rest of my system resources are fine. Running W10 with an RME UFX+ interface. Again, zero issues over the years including a long stint on this same PC with Cubase 11 Pro.
Debug files include the following clues:
ERROR_CODE: (NTSTATUS) 0xc000001d - {EXCEPTION} Illegal Instruction An attempt was made to execute an illegal instruction.
FAILED_INSTRUCTION_ADDRESS:

FAILURE_BUCKET_ID: ILLEGAL_INSTRUCTION_c000001d_Cubase12.exe!Unknown
Also, immediately after Halion crashes, if I try to relaunch Cubase I get a VSTConnect error (“Process with the ID NOT found”) followed by license errors that basically show no licenses were found for any of my VSTs across the board. I need to do a full reboot to recover from this. Once rebooted, everything opens and loads fine as long as I don’t launch those certain Halion SE 7 content sets.
No other VST on my system is having an issue including all third party VSTs from iZotope, reFX, etc. Halion SE 7 is literally the only thing not working correctly. And yes, I have tried reinstalling everything with no change.
Apologies in advance if this should be posted in the virtual instruments category instead of Cubase.
