Having the same issue since patch.

I have tried to uninstall and reinstall twice now.

Would love to be able to play.

I'm assuming you already tried launching with directX 11 instead of 12?

 

[longballoon]

Yes. Still gives the same error.

 

[A_Good_Bean]

Yeah just tried re-installing myself. I'm familiar with the fact that sometimes Alphas/Betas have bugs, but this is super frustrating since I can't even launch and literally donated for a key only a couple of days ago.

Yeah tried both, and verifying, and re-installing :/

Just to get it out of the discussion: you are on windows right? not linux of a mac?

Ew! Linux or Mac? God no but yeah, Windows 10

Also, if it helps;
Intel Core i7-8700K
32GB RAM
Nvidia GTX 1080

I have similar specs with the same issues yes on windows. I was playing prior to the patch.

I think this may have something to do with steam. Even though I have gone through and deleted all mortal online folders. Steam seems to only download the 35gb update when I install. Where it says the download should be 75gb. Can't find a solution.

 

[longballoon]

Finally got it to work, try deleting everything mortal related off the computer before you re install. After several attempts, I got it to work.

 

[A_Good_Bean]

Okay I'll try that

Any odd places you found Mortal stuff?

Hello,

Having the exact same issue!

 

[ChrisVaelor]

I have been deleting and reinstalling everything regarding Mortal Online 2 and Steam application in my PC, after reinstalling MO2 when launching keeps crashing with the same UE4 crash report.
I have Win10 Pro. Please look into this .

UPDATE: on my laptop MO2 starts normally, cant play though cause low specs. On my main PC I had Epic Games launcher installed.
I downloaded the Epic Games L. in my laptop and tried to launch MO2. Crash report from UE4.

So there is a compatibility issue probably with the EG launcher.
So far :
-I uninstalled the EG launcher from my main PC
-Reinstalled MO2, still UE4 crash.
Will troubleshoot further.

Worked for me too! Simply deleted all files and folders related to Mortal Online 2, then reinstalled, now works

Thank you for informing me on this...So I will try that too...the thing is that I have the MO2 directory folder from Steamapps backed up, and copied to steam root folder and reinstalling it, in order to save a lot of hours downloading it again.
Now I have deleted everything related to MO2 and redownloading it again. 11 hours to go...

Real solution, only install epic games and epic games services and solved your problems

Kill MSI afterburner before playing the game.
