Blueprints refuse to open — window opens and immediately destroys itself, no useful error
Hey everyone, been banging my head against this for a while and can't find a solution anywhere. I am working on a game in UE5 using both blueprints and C++ and all of my blueprints become inaccessible.
When I try to open any of my blueprints nothing really happens. I tried to see if the problem was that the blueprint window that was opened was too small but that is not the case. When I hover over the blueprint in the taskbar it shows the window as white and clicking it does nothing. No crash dialog, no useful error popup.
The only relevant log output I get is:
LogAssetEditorSubsystem: Opening Asset editor for WidgetBlueprint /Game/Inventory/UI/NEW_Inventory/WBP_PlayerHUD.WBP_PlayerHUD
LogSlate: Window 'WBP_PlayerHUD' being destroyed
LogSlate: Window 'WBP_PlayerHUD' being destroyed
LogWorld: UWorld::CleanupWorld for World_9, bSessionEnded=true, bCleanupResources=true
With verbose blueprint logging enabled I also see:
Generic delegate signature ref (InputVectorAxisHandlerDynamicSignature__DelegateSignature)
Before this happened I made some changes in C++ and than I had some blueprint compile problems. I fixed those C++ issues and the blueprints now compile with no errors — but they still refuse to open.
If anyone has any idea what is happening I would greatly appreciate any help.
Edit: I did manage to fix the issue by deleting the project locally from my pc and copying it again from my github repository. I assume there was something wrong with some of the generated files or something like that.
