A recurring crash issue in the Unity Editor has been observed, affecting various workflows. These crashes predominantly occur in operations involving the closing of the editor, changing input systems, and installing specific packages such as the new input system and AR core extensions. After a review of all relevant bug reports in our database, it has been concluded that this issue has been successfully resolved and no longer reproduces in active streams.
Reproducible with: 2021.3.30f1, 2022.3.7f1, 2023.1.7f1, 2023.2.0a6
Fixed in: 2021.3.31f1, 2022.3.8f1, 2023.1.8f1, 2023.2.0a7
Reproduced on: Windows 10, Windows 11 (by reporters)
Not reproducible on: No other environment tested
Notes:
1. A recurring pattern observed in these reports is the error logged in each crash report, which consistently displays:
"[Licensing::IpcConnector] License Notification channel disconnected successfully.
[Licensing::IpcConnector] License Client channel disconnected successfully.
Crash!!!"
This indicates a possible issue in the licensing system's IPC (Inter-Process Communication) connector just before the Unity Editor crashes
2. The determination of the 'Fixed in' versions was made based on an analysis of the last known versions that were affected by the issue
3. CQA could not reproduce the issue locally
