Happened to me after switching to 4.21.1 using the latest fmod engine plugin.
I just need to play an event once and the editor crashes when stopping the PIE session
I did not have this issue on 4.20

What version of FMOD are you using?

The latest engine plugin (1.10.10).
Also the events just get played in c++ like we used to do with the UE4 audio engine; we do not store the FFMODEventInstance which gets returned.

I will have to investigate this further, if you are able to send us the full logs that may help.

Hi. Our code team is also experiencing the same crash, especially with breakpoints. Has there been any progress in resolving this? We’re also using v1.10.10

It may be fixed in an update (as we are up to 1.10.13 now) although we weren’t able to reproduce the issue and we haven’t received confirmation yet.
Are you able to provide more information on the issue (eg. log files, repro steps, repro project)?

Thanks for the reply. I’ll ask our code team to sort out some details.

In case someone finds this theme too:
After migrating from 4.22 to 4.24 I’ve started to receive constant FMOD crash after the Play In Editor session.
What I did:
- Updated the fmod plugin (didn’t help)
- Updated the fmod studio (didn’t help)
- Disabled “Enable Live Update” in the Fmod settings in the UE (fixed the crash).
