- Exception message and full stack trace: Abp Studio crashes 2.2.4
- Steps to reproduce the issue: I have 36 projects in Abp Studio
System: Mac M2 Pro Max OS Version: 26.4 More Details:"template": "microservice", "versions": { "LeptonX": "5.0.1", "AbpFramework": "10.0.1", "AbpCommercial": "10.0.1", "AbpStudio": "2.1.0", "TargetDotnetFramework": "net9.0" },
In Abp Studio 2.1.4 no issues but after 2.1.4 version, all new versions fails so I always roll back to this old version 2.1.4
- While loading the abp solution it hangs (this is least possible)
- Most of time it fails to load the abp solution projects when I click solution shortcut, the abp studio crashes while loading the projects (Below is logs)
- In case it successfully loads the abp solution projects, while starting the docker container, the abp studio crashes (this is least possible)
Hope some logs could help, it happened with point 2 mentioned above

The log you shared shows ABP Studio backend throwing a NullReferenceException inside the Studio connectivity heartbeat pipeline (
IStudioHub/HeartbeatAsync→Volo.Abp.Studio.Connectivity.StudioBackendHub.NotifyHeartbeatAsync). That’s an ABP Studio bug/regression in newer Studio versions (not related to your ABP solution code), and it explains why it “sometimes hangs / crashes while loading projects” and “sometimes crashes when starting containers”.Since this is a Studio internal exception (and you already confirmed 2.1.4 works while later versions don’t), the only definitive “fix” you can apply locally is:
- Stay on 2.1.4 as a workaround (what you’re already doing), and
- Report it to Volosoft with the complete Studio logs so they can patch the regression.
What to send (so they can reproduce/fix quickly):
- The full ABP Studio UI logs folder:
~/.abp/studio/ui/logs
- The backend logs folder (if exists on your machine; include it if you see it):
~/.abp/studio/backend/logs(or anybackend/logsunder~/.abp/studio/)
- Your
.abpsln(ABP Studio solution definition) file for that microservice solution (if you can share it), and the approximate project count (you said ~36). - Your macOS version + chip (you provided M2 Max) + the exact Studio version(s) that crash (2.2.4 etc.) and the last known good (2.1.4).
- The full ABP Studio UI logs folder:

I have posted the logs for backend if it helps.
In macos, it happens > 2.1.4 crashes while loading solution's project in abp studio.
Hope some one from team could address the issue.
