1. What were you doing when you got this error?
2. Does it happen all the time?
3. Which version are you using?
4. Were you running more than 1 losslesscut at the same time?

Hi,
I had installed the 3.17.1 version, updated by donwloading the newest pre-release 3.19.0, and since then I can't do anything, the first thing appearing in the screen is the error

Re-checking now (1minute after the screenshot from above was taken), the error is gone.

Ok will have to look in to this. Damn Windows, always the one causing problems 😅
Btw it would be very helpful if you could answer all the questions

Been tracking this same electron-store issue on my app, which checks several local application version files against network files. I reduced the amount of writes to the json file (store.set) and it has gone away completely. At least I have not had any reports in the last two weeks.

Yea, my code is doing a lot of successive store.set operations. I suppose I just need to batch them and maybe debounce 🙁 I just hate the fact that every developer should have to go through this and then realise they need to rewrite their code after a user has discovered the error...
