I’ve done it successfully, but it was with a very simple project; all my other stuff was upgraded to preview 2 a while back, and so didn’t have to do an upgrade from all the way back in early access.
That said, what’s the crash information look like? Maybe folks can help figure out the cause from that.
I’ve tried converting to ea2 to preview 2 too but it crashed also. Was hoping would work with release… It’s not much its basically a template map with like weapon pickups and health pickups, some lava that does damage simple kinda stuff.
I moved my Project from UE 5.0EA 1 & 2 to Preview 2 and then to 5.0 Release canditate. Everything works fine with one issue, I cannot open my levels. Everytime I do it takes a long time to load, not sure if it’s gonna finish at some point. Later im gonna test it when I go to the mall and report. Though it seems like an unstable approach at the moment.
I did get my project to load when deleting the map and making a blank map before exporting but whenever i opened any blueprint it just crashed. I just really need to find a way to copy and paste or something the code to new project in ue5 release or something.
Unfortunately, it’s probably going to be very difficult for anyone to help without being able to look at the project; the crash log contains no actual resolved symbols to know where the crash is happening in any of those modules.
Failing anything else, I’d try deleting the Binaries and Intermediate directories and then trying to load again, just in case it’s a cached/compiled copy of something that’s gone wonkers on you.
Your project will be in a directory on disk; say it’s C:\Users\funkyspunky91\Documents\Unreal Projects\MyCoolProject or whatever.
Inside that directory, you’ll find things like MyCoolProject.uproject and a directory named Content and potentially directories named Source and/or Plugins. You will likely also find two other directories, named Binaries and Intermediate. Binaries is where the compiled binaries for your project live. Intermediate is where all the cached files and other stuff live.
My suggestion is that you try deleting those two directories – Binaries and Intermediate, specifically – thus causing the project to rebuild from scratch. Just in case that’s the root cause of your problem.
Binaries might not be there if your project is pure Blueprint, I’m not sure. But if there’s no Binaries directory and deleting Intermediate didn’t fix it, I’m not sure what else to tell you.
That’s the point where I’d probably run the engine under a debugger and step through the C++ code to figure out where the heck it was crashing. (And try to figure out a fix to submit as a pull request, if possible.)
