Hi everyone,

I updated my engine to 4.7.5, and I had a project that I was working on in 4.7.3. After I’ve updated, I couldn’t open the project file. It crashes at 96%. The other issue is that it doesn’t even generate a bug report, but I get a “Unreal Engine has stopped working” message from Windows.

Here’s what the Problem Details listed:

Hello CheersItsSheers,

After updating to version 4.7.5 and clicking on the project, did you use the “Open a Copy” option or did you use the “Convert-In-Place” option?

Try going into your Unreal Projects directory of the project you are experiencing issues with, and deleting the Saved, Config, and Intermediate folders. Be sure to make a copy of your project folder before deleting these folders.

Now try launching your project to see if the project still hangs and fails to open. If you are still having issues please let me know and we can continue to troubleshoot further.

Cheers,

Hi Andrew!

I did not try those before. So I went ahead and did both “Open a Copy” and delete the Saved, Config, and Intermediate folders.

And it works now! Thank you!
