Changing project version from 4.4 to 4.5 causes mobile preview to crash

I have tested through endless revisions of my project only to find that simply switching from the 4.4 revision of my .uproject file to the 4.5 revision of my .uproject file causes my Mobile Preview builds to crash on launch.

I have done a Diff Against between the two revisions and the only difference is the version (4.4 vs 4.5)

What in 4.5 would cause my Mobile Preview to fail? Let me know if there are any files I can provide to debug. Thank you!
