./dotTrace.sh attach --timeout=120s <PID>

Go to Rider and reproduce the issue.
Once the profiler finishes collecting a snapshot, the Terminal will show you where to find the snapshot files.Please add all of them to an archive and share the archive with the JetBrains team for further analysis. Use JetBrains Upload service to share large files with JetBrains.
