And then the app closes, usually loosing any edits in the template.

Expected behavior

@tonnydourado to give some context, the error is about a newly introduced config field called strict. Since the templates are stored in the config file, any update to the config file will trigger the validation and for some reason, strict field validation is failing. Could you look into paisa.yaml and check what's the current value of strict. I am still not sure what sequence of actions could lead to this error. Let me also know if you switched back to an older version of Paisa after the upgrade by any chance.

@ananthakumaran I have had strict: "no", pretty much from the start, and it still happens, sometimes. I also only ever used the latest version.

Though the error is very obvious (it tries to save strict with some value other than yes/no/""), I am not sure how it will go to that state. I had a quick look at the code, but I can't find any obvious mistake so far. If you could find a way to reproduce the error reliably, that would be very useful.
