Recently I've been using R2R's release to mix some audio tracks and I noticed that at least on W11 is very prompt to crashing under a lot of different circumstances that normally wouldn't be an issue on any other DAW.

• Want to change my audio driver settings while Cubase is open? Crash
• Randomly disconnected from the internet? Crash
• Opened another audio application like audacity while Cubase is running? Crash
• Try to open a project with a different audio driver than the one currently in use? Crash
• Add more than 2 simultaneous Insert FX on a track while playback is active (Pro C2 AND L2 in my case)? Crash
• Wake up my PC from sleep while leaving Cubase open? Crash
• Be just there doing other things while having Cubase open in the background? Crash

The only common symptom between all of these is that the post crash report Cubase shows on startup is that the crash was caused by SYSTEM32/MMDevAPI.DLL and OPENGL32.DLL, and since both of these are based the sys32 folder they can't be tampered with for sec reasons. The official Steinberg forums didn't had anything on crashes similar to these and since my laptop with W10 running the same Cubase version 14.0.32 is not as crash prompt as my PC, I'm starting to suspect it's a W11 problem.

If anyone has lead regarding these errors or found a solution to the same issue, I'd greatly appreciate it.

 

With all respect, if you use it regularly or professionally, pay for it. It is your main Tool where you'll host the others Microtools.

If that's not your case, then only be grateful for what you can try for free.

 

First I would make sure your Graphics Drivers are up to date.
I don't think it will be an issue with Cubase (R2R) as it works perfectly for me on Windows 11.
Next Open CMD Prompt or Terminal (as Admin) and do a scan by typing:
sfc /scannow
and press [enter]
If it finds any files that needs fixing it should fix them and you can repeat scan again to make sure everything is OK.
Scan for Malware using something like Malwarebytes (Free)

Also make sure you have the latest Microsoft Visual C++ Redistributable installed:

What audio interface are you using also?
Could possibly be related to Graphics card or an Audio interface driver issue if none of the above fix it.
