Anyway you can add auto save or auto save backup? I think it crashed on me and I hadn’t saved so I lost some work.
I can look into it. For the time being, check the “Temp” directory. Your project is saved to the “Temp” folder while the Designer is working on it. It normally deletes those files when the program closes. However if the Designer crashes you should be able to recover them from the Temp folder. The files will be in a folder with a random name. For example below, the random name was “1rl242vt.qgu”. Just do a sort by Date in Windows Explorer & you should be able to find your project fairly easily.
Found it, thanks. There were a few of them in there not deleted.
