Solved > Kernel Panic? after High Sierra to Catalina update

[Feartech]

I fixed the file system permissions using:

sudo chmod -R 755 /Library/Extensions
sudo chown -R root:wheel /Library/Extensions

Now, at least, I don't see filesystem permission issues.

I regenerated the debug. Can you please take a look?

I did these two things (installed FakeSMC and enabled the fixes) but still no luck.
