Android build crashes repeatedly upon launch or level loading before working

I am developing a mobile game with UE4 and am testing it primarily with my Android Moto G5 Plus running a rooted Android 7.0 with a build of NPN25.137-35. I can launch just fine, but when I open the app it crashes. When I open it again, it crashes. I keep opening it, and eventually it always works, and the app runs as it should, except when new levels are loaded it also crashes, but only sometimes. If I just keep trying to open the game or load the level it always eventually works. Moto G5 Plus Log

When I launch the game on my Nexus 9 (Android 7.11, Build N4F26Q, also rooted) it only crashes the first time the computer launches it, but gives the on screen error message “Message Failed to read file. Null Stream Line: 1 Ch: 0” then I press ok and back on the computer screen it says that it completed the launch successfully. I wrote in the attached launch logs when that happened. However, when I try to reopen the app on my Nexus 9 it always works, along with the level loading always working. Nexus 9 Log

I don’t know what to make of this, and although it isn’t interfering with development much, it is certainly annoying. Sorry if I gave too much build information and whatnot about my devices that you didn’t need, I wanted to be safe. I am also using UE4 version 4.17.2 and am developing on a Windows 10 PC, although you probably could have figured out the PC part just from how all my devices are rooted. The logs are attached.

Thank you for your time.
