I was having this problem on a 15" MBP 2019 with the Pro Vega 20, then again on the 16" 2019 MBP with the 8GB Radeon I swapped it for.


Basically, your Catalina install comes with a bunch of extensions for running RAID hard drives (most users won't ever do this). Something about at least one of them is broken. I haven't worked out exactly which ones cause the problem, but they can all be safely removed if you don't use RAID HDDs.


They can be found in MacintoshHD>Library>Extensions. Make sure you're looking the right right Library folder, you want the one on in Macintosh HD, NOT the one under your username. I made a backup of them just in case, then cleared out the following .kext files:


ACS6x

ArcMSR

ATTOCelerityFC8

ATTOExpressSASHBA2

ATTOExpressSASRAID2

CalDigitHDProDrv

HighPointIOP

HighPointRR

PromiseSTEX

SoftRAID


Since I was on a very fresh install, I expect these are all the ones which come with Catalina as standard. My machine has since been waking from sleep successfully and quickly every time, even with multiple displays and USB-C devices plugged in.
