I have uploaded the log from my last crash here https://gist.github.com/ZornTaov/7625bfa787f098266f6ab0a54968bb7a and I can confirm that removing the “missing file” entries from saved/config/windowseditor/editorperprojectusersettings.ini fixed the crash. It’d be a good idea to add a sanity check and make sure the file exists before adding it to the recent menu, otherwise remove that entry from the list.
As an aside, it’d be great if this functionality was extended to other asset types. I’m using the Logic Driver Lite plugin to add state machines to my game, and they don’t appear in your recent list because they’re not “blueprints” per-se.
