Please try adding boot-arg slide = 0 and clear NVRAM again, then try booting.
added slide = 0 to the boot-args and pressed F11 again before booting. No change unfortunately. I was going to test Mojave and see if that would boot, then troubleshoot from there.
UPDATE:
Got the same kernel panic on Mojave. I changed my graphics settings like you told someone else to do in an earlier post
"- DVMT Pre Allocated to 64MB
- DVMT Total Gfx Mem to Max (or the highest value) "
I then tried to boot and it hung in a different spot. I could not replicate that hang and I am currently getting the same kernel panic even with the updated graphics settings
FURTHER UPDATE: I've gotten it booted and installed. The trick for me was to create the USB recovery stick, but only copy over the files in the "kexts" folder of the hackintosh guide. Additionally, I did not overwrite the fakesmc kext that was already on the usb stick in "kexts" folder. Booted and installed with no issues. Now updating from the beta to the full version of Catalina. Hoping that goes smoothly!
