Migration from 5.2.1 to 5.3.2 - Crash

PrexCoder · February 9, 2024, 9:53pm

Hello, recently ( 2 days ago) I’ve tried to migrate my project from 5.2.1 to 5.3.2, so I’ve followed the guide that’s available on epic

Unreal Engine 5.3.2 → Launch → Open the 5.2.1 Project → Open a copy → All Good Here.

A new copy was created in a new folder called projectName 5_3, so I start UE5.3 and launch the project, and here is the point where my life takes a new turn, if I click on any Blueprint Idk bp_gamemode, any bp at all, the engine will crash with the error that I will provide at the bottom, if I try to create any bp in this project and open it, it will crash with the exactly same log, I’ve tried to migrate using the well migrate functionality from 5.2 to 5.3 same problem, if I run a new clean project it’s all good, but I got lots of things here and I’m out of options, any ideas how can I sort this out?

I don’t know if I can share files here too, but if it’s needed I can share some samples so you can test this thing on your side too, a big Thank you in advance

Hey @PrexCoder!

Did you get this solved? Try making a post about it as well- this is something the greater cloud might be able to help with more. All that I personally can figure out is that it is an issue with SourcePin- WHICH is pretty strange because “SourcePin” is just the code name for the input pin on any cast node.

How many times have you tried to do the “Open a Copy” method? It sounds like a file got corrupted with the migration, which is common and why we recommend doing a copy. (I mean I think people should back up the entire project every day it’s worked on but that’s just me.)

Hello,

No, I did not find any solution for this problem, I decided to stick to 5.2 judging that I can’t migrate to 5.3, I’ve tried “open a copy” just one time and this problem started to show up, after that I’ve tried different solutions all of them ending up with same problem, and I use svn in order to be sure that when I do such changes there is something that keeps my project safe, so It’s all good, the only thing Is that I can’t move to 5.3

Mind-Brain · February 14, 2024, 10:09pm

Hey, that’s possibly good news! I mean if you’ve only tried it once that doesn’t necessarily mean it’s broken. I would try three times, if you get the same error then you know for sure this is an issue.

Moving up versions is somewhat difficult as everyone’s projects are different. Sometimes you do have to make small adjustments to fix a large thing before migration, but usually it’s very possible.

Hello, I encountered the same problem as you, and it was during the transfer… And I found a solution to this problem, maybe you have the same thing)
In the Screenshot, an array that includes a single pin.
And the code is located separately from the main line, because of this the editor does not see it as an error, and when transferred, the compiler reads everything and crashes.
