The new Update crashes whenever I want to open the File Menu.
It also crashes now whenever I want to open one of my Assets or I want to test the game.
The CrashLog (when I want to play the game):
Is there a possibility to force a full cleanup of a project? That means a full rediscovery of assets, clearing Shader cache etc that reintegrates all necessary files?
Edit: I’d also like to downgrade from Preview 3 to Preview 2. Since Preview 3 is way too unstable to work with.
As far as I know there is no way to downgrade engine versions in the launcher. The only way I know of is to pull the tagged version from github and compile it yourself.
In your project folder you can pretty much delete any of the following folders (.vs Binaries, Debug, DerivedDataCache, Intermediate, Saved) as well as any Visual studio (or other IDE project files .sln .sdf and then if you have c++ code with your project right click .uproject and do “Generate Project Files” then you can restart the editor and it will for sure rebuild shaders, content and any source.
Basically just make sure not to delete Plugins, Source, Content, Config, or the .uproject file
As always, make a backup of your project before trying any of this.
Hi Raildex,
I do not have a lot to add to what Koderz has already said but if you have a project that you started in UE4.12p2 that is consistently crashing in UE4.12p3 this could be useful for identifying the source of these issues if you were willing to share it. If so, you can send a link to your zipped project folder to me in a private message on the UE4 .
Wow just had this happen to me , Thank goodness I had backups , I just migrated all the content I had been working on over to the backup.
This is what happened in my case … - Working on 4.12 p3 - Had crash while importing mesh with morph targets - When loaded back up the project the file button causes instant editor crash
