Thanks for this -
That error is actually related to the auto-updater not being able to find an internet connection to check if there’s a new version. It’s throwing an error early in the main thread leading to other UI events not registering - including the event we listen to for file loading. That would explain why it’s happening intermittently/such a small subset of users: most people have a internet connection active. It also makes the issue relatively easy to reproduce - disconnect internet, attempt to load file, validate if dialog appears. We should be able to fix this relatively quickly.
Thanks for your help!
