@Adriani90 The NVDA version is 2024.4.2, but all my changes were introduced in 2025.1. So I don't think this issue is related to my changes. Anyway, I think that it would be helpful to clarify the meaning of "crash". Was NVDA terminated automatically? Or did NVDA stop responding, requiring you to stop it? From the log, it seems that NVDA was stuck when cancelling SAPI5 speech. |

@gexgd0419 NVDA terminated automatically, it disappeared from system tray and it's keyboard shortcuts didn't work at all. |

The issue reoccurred again: |

Hi, In the last few lines of the old log, it appears system process is dying and took down NVDA with it (or vice versa). Also, does this happen if you use another speech engine or voice? Thanks. |

@josephsl I can’t stand using eSpeak engine! Unfortunately, there aren’t many good voices for Greek language... |
|
Hi, I see. However, this is a situation where we need to try something even if we don't like it, thus I would like to kindly advise testing with at least Windows OneCore or something other than SAPI5 so we can isolate the problem. Thanks. |

Does this log help more? |
Steps to reproduce:
NVDA crashes randomly between irregular time intervals, i.e. it may crash twice during the same day and then recrashes e.g. after 10 or 20 days. I haven’t found any certain circumstances under which the problem occurs. The only think that I noticed is that with debug logging level enabled the issue occurs more rarely, but I’m not sure if that was coincidental.
Actual behavior:
NVDA runs continuously in the background without crashing and terminating itself.
Expected behavior:
NVDA crashes randomly needing to be restarted manually.
