Unable to fix sleep

[bin0]

I've got an XPS 15 9570 with Catalina 10.15.4 and OpenCore 0.5.7.  Whenever I try to sleep from the menu, the screen goes black and it rapidly returns to the lock screen.  Whenever I leave it unattended long enough that it sleeps on its own, when I try to "awaken" it, the fans get very loud and it refuses to come back up.  When I re-boot, I find there's been a kernel panic with the following information: https://f.jr0.tech/panic0.log

 

Please let me know if I can provide any information and if you have ideas on how to fix this.

 

Thank you.
