Repro project:
MonoModRepro.zip
To repro:
- open with rider and run with debugger (i have rider 2025.3.0.3)
- wait like 1-3 minutes
- get the stack trace in console and dotnet crashdump trigger
Let me know if you want the process dump, just due to the nature of my repro the dump file itself is around 5gb.
