Unreal Engine crashes when selecting map

Hello!
When I click on the specific map in my project, the engine crashes. It also crashes when I go to project settings and change the EDITOR STARTUP MAP to same map. I really don’t know what is going on… I am using Unreal Engine 5.0.3
The attached picture is the log which I am getting when lauching the engine.
Please help!

Greetings @slycrespo2

With the specific error you’re showing there, I’d recommend taking a peek at Error: Error in Feature pack C:/Program Files/Epic Games/UE_5.0/FeaturePacks/TP_VirtualRealityBP.upack. Failed to parse manifest: Invalid Json Token. Line: 43 Ch: 4. There are several solutions offered there and a few seem to have remedied the error. Let me know if that fixes it. Thanks!

Hello!
Thanks for your reply, but I have tried everything that is written in the link you posted and nothing is working. I also updated my graphics card drivers and still no success. What else can I do? Please help!

As a possibility - crash may be caused by content of the target map, which can unfold into thousands of possible reasons. Do you have a crash callstack to share?

What is crash callstack?

Please help someone…

Hi @slycrespo2

Is there any more text below in the error that is not shown in the screen shot you provided? Also, I’d double check and make sure that you have .NET Core 3.1 installed. It’s a requirement I’ve saw before with the TP_VirtualRealityBP.upack failing to parse manifest etc. I’d start there. Also, if there is any additional lines below the ones shown in the screen shot, could you post those? Thanks!

I am attaching the log file here if it helps.

That’s quite unusual place to crash, but…

missing assets have quite a chances to be a reason for crash

As about how to fix it? Idk your project internals, so the most brutal way is to remove blueprints(and other assets) that refer missing assets and recreate them from the scratch. If you don’t wan’t to recreate this part from scratch, then either try to fix it based on your project either rollback to last working version. You did have a VCS setted up, right?

I have successfully removed the following assets from the Content browser:

‘/Game/Main/3DModels/Ostalo/TablaSmeti/

‘/Game/_Main/3DModels/Vozila/Traktor/blinn1’

But when I try to remove (or open):

‘/Game/_Main/3DModels/Ostalo/MotornaZaga/chainsaw_alpha’

engine chrashes. What could I do?
