My unreal editor gets stuck at 75% when I try to load my project up. I’ve tried deleting my binaries and intermediate files and recompiling the entire solution in visual studio but it still doesn’t work. I don’t think it’s compiling shaders because it’s not using any CPU or GPU when I look at the process in task manager. But the reason it hangs is always different, each time I try to load up the project. Sometimes its “verifying objects”, sometimes it verifying some kind of Niagara file (as shown in the picture), sometimes it’s “compiling blueprints”, etc. Regardless of the process it says it’s doing, it always hangs at 75%. Is there a solution to this? ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/b/b/bbbdfacbc2c980ebeb7d074edbe06ac96dd81ca8.jpeg) ---

I have the same issue. Have you tried: • Opening the .uproject file from your computer directly • Opening the project directly from Epic Games Launcher • Launch Unreal from the Epic Games Launcher and then select your project from there and launch it These worked for me. ---

I have my project on my secondary drive, which has 820 GB free, but epic games launcher is installed on my C: drive which is nearly full. I could try deleting some stuff from my C: drive to see if that fixes it ---

-Since now you have some free space - try waiting for at least 30 minutes for the editor to launch -Delete Saved folder -If nothing helps - you can copy-paste the Content folder into an empty project ---

you can look in the log file and see if it’s doing anything. or launch it from a command line with the -log parameter and it will open a window with the log, so you can s ee what’s happening in real-ish time. ---

I tried these, but when your final suggested solution didn’t work (copying the Content folder over), it gave me an idea. I just went through and deleted a few of the different blueprints I most recently made in the project, one of them being a “GameMode”, and deleting that seemed to fix the issue. Thank you for the tips! ---

Hello, by any chance were you able to resolve it without having to delete the GameMode? In my case, it also solved the issue, but I don’t think deleting all the work done there is a viable solution. ---

I got stuck at 75% several times with totally different conditions. It seems to be a thread Bug with UE5. Generally I need to delete some assets or C++ codes to restart the UE5 editor. No idea why this happened. e.g. recently I made some class finding code in one of my character A, static ConstructorHelpers::FClassFinder scvWidget(TEXT(“WidgetBlueprint’/Game/BPCpp/Race/human/Units/BP\_ProduceScv.BP\_ProduceScv\_C’”)); if (scvWidget.Succeeded()) { arrWidgetsClass.Add(scvWidget.Class); } where TArray\ arrWidgetsClass; It is quite simple, and I copied it to another character B, then my program stuckn at 75% percent. The funny thing is that, I can repeat this stuck with the following condition, if I comment out the code in B, UE5.4 will work fine; if uncomment, got stuck at 75%. My suggestion is, check what you did after your last successfull startup. ---

Engine loading was hanging at 75% due to a classic **“garbage-in-garbage-out”** problem. In my **USTRUCT constructor** , I used **uninitialized `int32` variables** as the **MAX condition** for my iteration loop. Due to **garbage values** in those fields, the iteration went **infinite** = 100% CPU hang at 75% engine loading. `for(int i = 0; i < UninitializedInt32; i++) // i < 0xDEADBEEF = billions` fix was to initialize my variables before use.
