You should be able to download and install the Editor from the Archives. Using the launcher, click the + button and it will set a Editor version you do not have, then on that new icon, click the Down arrow icon, that will reveal a drop down menu of previous versions not installed.
If you want to use projects made with 5.5.2, you may need to Migrate, or Export those Assets first.
Right click a selection or singular asset in the 5.5.2 project, chose Asset Actions… then you have two choices.
Migrate transfers the asset and its dependencies to another project, or Export gives you a sort of zip file equivalent file to load into another project. In my experience the Export breaks all the node links in a Materials file.
Another method is to Load/Launch the 5.5.1 Editor and when you are shown a menu of all projects to open, click the 5.5.2 project and it ‘should’ make a copy and open. This should work, given that the Editors are only 0.0.1 branch apart.
HEy thanks for the reply, my issue is that the launcher only contains the latest version of each Big Update: 5.5 \ 5.4 \ 5.3 and not the small updates :

Try deleting/removing the 5.5.2 editor then use that method to get the 5.5.1 you want. It should not do anything to the 5.5.2 projects.
Hmm… I tried checking the Unreal Editor/Engine archives, nothing available. Do you use Windows Restore? Bit of a crude way of doing things, but might work. Last resort really.
I checked my own Backup system, nothing there, all overwritten by 5.5.2
Maybe if you can explain why you want to roll back, someone could give advice.
I have been unchecking all the ‘Experimental’ and ‘Beta’ plugins that are installed and turned on by default, it does make things a little less crashy. All except the Browser ones, that you need to open Plugins :P…
May I ask why you would want to go back to UE 5.5.1?
It might help others not get stuck in your situation.
well, for some reason 5.5.2 does not let me change any Structures without breaking the project build.
i can still play in editor but i get an error while building:
LogOutputDevice: Error: Ensure condition failed: DefaultStructInstance.IsValid() && DefaultStructInstance.GetStruct() == this [File:D:\build\++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\StructUtils\UserDefinedStruct.cpp] [Line: 476]
LogOutputDevice: Error:
i was not able to fix. and every struct i change brakes Building. i even made a new project, and as soon as you make a struck with a map | Struct2 and change the struct2 the engine gives that errors when building.
So the solution?
duplicate the project, open the project2 make the struct changes there, and then copy the UASSETs to the original project.
BUT ONLY THE STRUCTS
Hey there @vyzor! If you need specifically any non-top end hotfix version, you may need to build it from source. If you already joined the Epic Games team on Github, you can skip the first link below. If not, you’ll need to link your Github to your Epic account to be able to see the link to the 5.5.1 source.
