Editor crashes every time I'm trying to play

[3xist3nc3]

Hi peeps,

I’ve got a problem, and hoping for a little help

Branch: I guess it’s a ‘Binary’ build from the Unreal Launcher. It’s NOT from GitHub, at least.

Build version: 4.6.0-2369412 (however, the problem started in 4.5 - I changed to 4.6 hoping it would be fixed, without luck.)

Detailed description of the issue:
I’m working on a game, and had gotten a few things done. For example, I followed a tutorial created by the UE team, on how to create health and healthbar in UMG. I mixed this with the experience-bar-thing, and made it so the Player loses some life every move he makes. This life can be regained when entering LifeForce stations. This worked like a charm.

Next thing I wanted to do was create locked doors that could only be opened after picking up keycards. I got help on how to do this, but unfortunately, early in the process of this, the game just started crashing every time I tried playing - the engine crashes before even launching the game, no matter which play Mode I try. Well, if I play as Standalone Game, at least only the new window crashes and the engine keeps running - otherwise, the whole thing dies.

Now, I have created the “keycard opens door” in many other projects, and thus know the procedure works and doesn’t crash the engine + this specific game project didn’t crash before. So I tried removing all the blueprints and items added after the crash started happening, but it still crashes, as if the game itself has been infected with some kind of weird virus.

It was a pain to set up the lifeforce-draining functionality on the player character, so I really hope there’s a way to fix this crash without having to create the project from the bottom again.

As there are no specific blueprints I think is causing the crash left in the project anymore, I have no idea what causes it, so not including any screenshots right now. However, I’ll provide anything you need if you ask.

Hello 3xist3nc3,

The first thing I would like to help with is the recovery of the assets that you need to continue working on your project. I have a couple of solutions that you could try.

Solutions:

1. From what you have told me, it seems as though you can still open the project. If this is true you can right click the assets that you would like to use in another project (one that is not crashing) and choose the “Migrate” feature. This will move all relating content needed for this asset to the new project that is chosen.

2. The editor creates backups automatically and with any luck you can go back to a point before the project was crashing and start from there. To find these backup files you can navigate to the saved folder which can be found in your project folder. The default directory is as follows: C:\Users\YourUserName\Documents\Unreal Projects\YourProjectName\Saved\Backup

Quick questions:

1. Are you receiving any errors?
2. Can you reproduce this issue in a clean project?
3. Can you provide accurate steps to reproduce this issue?
