HALion Sonic 7.5 crashes DAW

HS7.5 crashes DAW after removing its instance. Reproducible as follows:

CUBASE 15 SCENARIO 1:
create new project
create new instrument track with HS7.5
load Sonic Selection preset “80s Piano Layer” into HS7.5
close HS7.5 UI
reopen HS7.5 UI
while UI is open, remove the track or close project
->crash

CUBASE 15 SCENARIO 2:
create new project
create new instrument track with HS7.5
load preset “80s Piano Layer” into HS7.5
while UI is open, save project
close project
reopen project
close project
→ crash

REAPER 7:
create new project
create new track
insert HS7.5 into track FX
load preset “80s Piano Layer” into HS7.5
close HS7.5 UI
reopen HS7.5 UI
while UI is open, remove the track or close project
→ crash

  • I choose always the same preset as anchor, but any preset would work
  • Cubase randomly survives the scenario, repeated testing is necessary.
  • Reaper is always crashing.
  • Testing H7.5 the same way: no problems.
  • Previous version of HS: no problems.
  • So only HS7.5 is affected.

Tested on Windows 10, clean new software installation, appdata folders emptied, no 3rd party plugins, factory default config, software/drivers all up to date.

P.S.
With kind regards to the quality assurance and testing team!
I mean, this bug is so obvious that it blew up in my face within the first minute of testing. And then it took me a whole day checking all possible causes to pinpoint the problem. Isn’t that actually the job of the testing team, before software release?*

Thanks for testing and the detailed steps to reproduce the issue.
Unfortunately, I am unable to make HALion Sonic 7.5 crash - in both Cubase and Reaper.
Admittedly, I am on Windows 11 with no access to Windows 10.
If HALion Sonic crashes, are there any crash dumps that you could send?

Both Cubase 13, 14, and 15 have recently been crashing upon closing since I started using HALion Sonic 7.5.

I reinstalled HALion Sonic 7.1.51.1043, and everything is fine again.

Attached is a ZIP file containing two crash dumps (Cubase 13 / Cubase 15).

Hello. I’d really like to install the latest version of HALION Sonic (7.5.0)—that’s what’s being offered to me in the Download Assistant. However, I’m hesitant to do so because of the problem already mentioned in this thread. I’m checking back in just in case anyone has a new idea. Best regards…
