Also upgraded from 10.14.3 to 10.14.4 and all my kexts in kexts/Other; however my hackintosh does not get past the Apple logo now. I've upgraded from 10.14.1 to 10.14.2 to 10.14.3 with no issues along with updating my kexts, aside from rebuilding kextcache for touchpad to come back to life.
The kexts I updated along with 10.14.4 were WhateverGreen, Lilu, and AppleALC.
The first error message was "HASH data from ME never returned", which I got past with -disablegfxfirmware in boot args. After that I'm stuck at AppleACPICPU timeout / IOConsoleUsers: gIOScreenLockState 3.
My config.plist and kexts/Other is identical to yours; the only thing I did not update was the Clover version. My clover is at Clover_v2.4k_r4844 versus the current 4895. Not sure if that's the problem. Is there a way to update Clover from Windows?
Another solution I can think of is replacing WhateverGreen/Lilu/AppleALC with the previous version. I can mount EFI from Windows, but I don't have write permissions to mv/move the older version from my Windows drive to the EFI drive even with an elevated command prompt.
