16 Inch Macbook Pro Bad Magic Crash when attempting to restart

[LincolnsiPod]

My MacBook crashes every time I attempt to restart it. Shutting down works fine, but restarting results in the MacBook gagging halfway through: it'll begin to restart after the screen shuts off, then the fan gives this weird puff, and suddenly the MacBook turns off instead of rebooting. When i turn it on manually and login I see a bad magic error:

BAD MAGIC! (flag set in iBoot panic header), no macOS panic log available

Restarting from the login screen (before I log in) also seems to work fine, so maybe something being loaded at startup is interfering with the rebooting process.

Anyone else experience this and found the cause?

I saw that but I don't think it's the same issue, my MBP doesn't randomly crash and isn't connected to eGPU, it only occurs when I try to reboot it. It also fails to restart without being connected to any peripherals too (e.g. backup drive, external display).

What I got from the thread that I linked, was that they thought it was a hardware problem. I would recommend you contact Apple to have your MBP tested.
