Thank you very much for reporting! This crashed your computer completely? Maybe this is related (even though the app is not using Dexie): dexie/Dexie.js#271

Here is the related code in chromium: https://chromium.googlesource.com/chromium/blink/+/e8b15b4ccd4258b073d564aebe1bba96a5609c75/Source/modules/indexeddb/IDBFactoryBackendImpl.cpp

Hello. It didn't crash my computer, only the app itself. I couldn't use it until the computer restart.

[johannesjo]

I was unable to reproduce the issue and also didn't find an obvious fix for this after an extended research. I updated electron however as there are several issues fixed with 8.3.0 which might be related. I also improved error handling in case this occurs again.

I leave this open for now. Please let me know if the error occurs again.

[johannesjo]

I just came across this myself. My problem was running two instances of the app, which caused the database access to fail. This should not be possible any more following the next release.

[cristianharangus]

It may be that the app crashed for a different reason, and I was trying to just reopen it when this error occurred. So yeah, basically two instances of the app causing db access to fail. Most likely this was my problem too.

[johannesjo]

May I ask if you encountered this or a similar issue again? I am asking because I had the feeling that this might have gotten better with the most recent electron version (introduced with Super Productivity 5.6.5) as nobody has reported a similar issue after that.

[johannesjo]

I added some advanced data repair/restore functionality, as a compromise as there is no way to fix this completely without replacing the database adapter, which is not trivial and likely to cause new issues on other fronts. I think this is acceptable, as the issue only occurs rarely. I am closing this, but please open up new issues, if you encounter this again. Thank you!
