Darktable doesn't open

Software darktable
1

Recently I tried to open an image I was editing in Lightroom in Darktable.
It didn’t and since then, when I try to open Darktable I receive a message which I transcribe below:

An unhandled exception occurred.
Backtrace will be written to:
C:\Users\chris\AppData\Local\Temp\darktable_bt_U4KO12.txt after you
click on the OK button.
If you report this issue, please share this backtrace with the developers.

How can I solve this? I have already uninstalled and reinstalled Darktable, but the message persists and the software doesn’t run.

This is one of the backtrace content I received:
this is darktable 4.6.0 reporting an exception:

I don’t have the knowledge to say why it happened - but as to ‘resetting’ stuff, uninstalling and reinstalling has no effect, as all the darktable operational files are stored elesewhere.

On windows, Darktable configuration files (and the library and database) are stored here: C:\Users\USER\AppData\Local\darktable (so in your case it would be C:\Users\chris\AppData\Local\darktable

The kernels are stored here (hidden system folder)
C:\Users\USER\AppData\Local\Microsoft\Windows\INetCache\darktable
The logs, (if you enable logging by starting dy via the command line) also go here.

If you delete or rename these folders, darktable will start with everything set to the defaults, but you will also loose any customization and you’ll have to reimport your images.

Hi, Steven.
Thanks for helping, but I cannot find the folder \AppData, don’t know why.
I will try to discover if it is hidden.

Oh… I think it is hidden. I’ve got all the ‘hiding’ settings turned off so I forgot. If you copy and paste or enter manually the address in the address bar in Win explorer I think it’ll take you there anyway.

It was hidden.
I found the folder, deleted it, and Darktable is running again.
Thanks a lot for ur help!

Great! I’m sure others can help further to try to figure out what caused the issue, but glad it’s running again.

If deleting configuration data, database files and cache “solved” your problem, this indicates a problem with your personal configuration. To really solve this problem, not just work around it, it would be necessary to analyze the actual cause of the crash on your computer with your specific settings and databases.
