Install Size vs Size on Disk - Unusable after multiple install attempts

[VerdantPrecipice]

I’m having a very strange issue with installation to my M.2 SSD. First time using the program since 5.0 launched. The download says its 14.8 GB, but the download takes ages every time and freezes for periods of hours. 5.5.0 failed to install at all, but the downloaded files were taking 288 GB of the 289 of free space. After numerous attempts at installing 5.5 and two attempts at 5.4.4, I finally have 5.4.4 installed.

In its initial state as installed, under properties, its size was 35.6 GB, but its size on disk was 220 GB. I have never seen this level of disparity before. The only relevant forum post I could find was this: Unreal eating up 115 GB of disk space from back in '22. I followed the steps here, toggled off every extra option and recompiled. This ballooned the size to 143 GB and the size on disk to 326 GB, even though that is more than the free space available before install. I then toggled on engine source according to their troubleshooting, and it took it down to 31.5 GB and 213 GB size on disk. I haven’t installed any assets, my vault is empty, and this isn’t even the version I set out to use.

After launching the program and compiling shaders, it crashes immediately after the full window opens. This is my crash log.

This doesn’t seem to be an issue with my SSD, as everything else on there is running perfectly fine. The incredibly poor download speeds weren’t related to my connection either. This has me stumped. Any assistance would be greatly appreciated.

P.S. Waited over an hour for the first post to get approved, not sure what’s going on there. If both go through, please delete the first one.

Hey there @VerdantPrecipice! Welcome to the community! The error you’re experiencing might not be related to your possibly failed installations, as it’s a graphical DLL being referenced. This doesn’t 100% mean it isn’t related however because if the shaders are broken it might still cause something similar, but nvwgf2umx is referencing a specific Nvidia library used in rendering. Here’s a thread to help solve that crash (independent of the issues you’re having):

Hey there @DSchultz2000! Welcome to the community! So the nvwgf2umx portion of this error refers to an Nvidia graphical dll. So more than likely it’s related to GPU settings or drivers. Most time’s I’ve run into this, the fix comes from a few possible angles. Listed in order of most common to least common known fixes: Defaulting your Nvidia 3D settings Disable G-sync in the Nvidia Control Panel Changing to Studio drivers instead of Game Ready drivers (For laptops) Disabling whisper mode in Ge…

However when it comes to the storage issue, it’s possible that some temp files weren’t removed after installation attempts failed or that everything including editor symbols was installed. When anything is being installed on windows, there is a temp location in which the files are downloaded to, then when fully downloaded they are unpacked, placed where they should be, then deleted from the temp location. If this failed it’s possible those files are still remaining. This seems plausible that you ran out of space during the operation.

If the install completed, what is checked in the launcher under the options for the version(s) you’re using? This can easily double the engine install size and depending on the build targets chosen.
