My 2019 15inch MacBook Pro with Vega 20 always crash and reboot when it going to sleep. And each time It automatically change "switch the graphics card" option in powel setting to uncheck.

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.
It won't. I tried that first.
Catalina have a lot of problems , this is the reason why I not update my MBPmid2014
Same here - constant crashes
It appears that my Mac is still fully functional after a full overnight test. I think using this application may have fixed the issue for now.
Well, that's not a fix but a workaround circumventing the actual issue ...
Same problem here. Only started happening when upgraded to Catalina.

@timjtim, Amphetamine is not useful for laptops (like mine):
Tony, I followed your suggestions and - after a week - I have no crashes at all!
Thank you.
I just saw the new update has come in. Has anyone tried it yet?
Has anyone had any luck with sleep issues going away?
I fixed the issue on my MBP by selling it to my brother-in-law. lol.
That works also JKN1 !
Same! Except my enclosure is Thunderbolt 3. It happens even if they aren't connect though, so I don't think it actually has anything to do with them.
I confirm. This worked for me too.
Hmm. What attached devices that caused crash before your update? OWC Thunderbay RAID Drives like mine? Or? Maybe we have different reasons for sleep crashes.
Sometimes it also crashes out bluetooth. Does anyone else have that issue?
