Unhandled Promise Rejection

Using a supported version?

• I have searched searched open and closed issues for duplicates.
• I am using Signal-Desktop as provided by the Signal team, not a 3rd-party package.

Overall summary

Clicked X multiple times to close, then crashed with an error every time I tried to open

Steps to reproduce

1. I had a chat open
2. Pasted a screenshot
3. Added an emoji
4. Pressed enter, but noticed that it added a new line rather than sending it
5. Tried to close the app, but the window didn't close, so I pressed multiple times the close button
6. I tried to reopen the app, but got the error I posted in "Actual result"

Expected result

Normally it closes and opens up as usual
I fixed the issue by terminating Signal's process and relaunching the app

Actual result

Unhandled Promise Rejection

Error: EPERM: operation not permitted, unlink 'C:\Users\avi12\AppData\Roaming\Signal\logs\app.log.3'

@avi12 is this reproducible for you?

[avi12]

Sadly no, ever since I terminated Signal's process and relaunched it, it's not reproducible

I had a similar issue - the same error message, but with app.log instead of app.log.3. I couldn't see any information about app.log using icacls or takeown. I used File Locksmith from PowerToys (as recommended here) to see what had locked something in the logs directory. It found that there was a signal.exe still running, though there was no sign of it. I terminated that and Signal was able to start fine again...

@davidfraser We'd love to see debug logs for the situation you've described. It seems like Signal Desktop is taking too long to shut down, and also not properly detecting a second instance before starting up!

[davidfraser]

OK, this only happened once yesterday - here are the logs I can get, but it seems they only include the new session, not the dead one: https://debuglogs.org/desktop/7.10.0/e08e4d3bf90f6d897ca438498dfcb1b629edddc66fa26163b18c6f52cfa870e1.gz

@davidfraser Thanks for the debug log - it looks like you did have a crash or somehow ungraceful exit. But we don't have any information about it. If you start using the app with the --enable-crash-reports command-line argument, your future debug logs will include crash information.

I turned on debug logging, and then got told that there was a crash - logs here although I don't think this was the same event

@davidfraser looks like thats a different issue with EXCEPTION_BREAKPOINT, it looks like this happened soon after a network connection was reset. Did you make any changes to your network before this happened? Such as changing wifi networks or turning a VPN on/off?

WARN  2024-06-01T01:01:27.750Z WebSocketResource(authenticated): WebSocket error Error: read ECONNRESET

[davidfraser]

Hmmm, I didn't switch networks at that point. So I'm not sure. But will upload another debug log if I get into the same situation as reported in this bug originally

[avi12]

A friend messaged me on Signal, I got a notification on mobile, and then I switched to the desktop app but noticed that it wasn't synchronized for some reason
I tried to close the desktop app, didn't respond the first time so I clicked X a second time and a moment later I got

app.log

I tried to reopen Signal on the desktop, got the error again
I suspect that similar to my original post, the only way to work around it is by terminating the Signal process

[indutny-signal]

@avi12 sadly, this is very likely true. If you'll attempt to terminate it - could you make note which processes were running? So far we lack this information and it is hard to take action on the issue.
