Dungeondraft gets into a state where it can't show any menus

I'm not sure what causes it but Dungeondraft appears to get into a state where it can't show any menus because it's instantly closing them, this applies to menus like the main menu in the top left and also to things like the terrain menu or object menu or the New Map dialogue. So far the only thing I've found that resolves it is restarting my entire computer.

This most recent time it happened again shortly after loading several new asset packs on a map where some of the assets had gone missing so perhaps it's related to memory usage?

I'd appreciate any advice on how to prevent it, work around it, or resolve it without having to restart everything, thank you.

I'm on version 1.0.3.2 on Windows 10
