That’s great! Let’s do it this way then:
- Create a new blank project with UE 5.5
- Enable all the plugins that you use in your UE 5.4 project
- Open up your UE 5.4 project and migrate all of your assets into the new blank project.
You can migrate assets by right clicking on them, navigating to Asset Actions on the menu that pops up, selecting the Migrate option, clicking on OK while keeping all of the asset’s dependencies as selected, and then selecting the new UE 5.5 project’s Content folder as their new home. You can also migrate assets together or select a folder as a whole. The migrate option won’t be hidden under any additional menus if you right click on a folder.
If the new UE 5.5 project crashes and you’re not able to open the .uproject file with this approach as well, then try migrating your assets in separate bulks and see which ones cause the issue.
Hope this helps!
