I upgraded a few weeks ago to 2024.5 (not plus). Since then, I have been experiencing crashes under the following conditions:
PC Powered off for a while
Power On, Load into an iRacing session
after ~5mins, PC screen goes black and reboot begins.
(after the crash reboot, i can use the PC normally without issue until next power down)
MS events:
The computer has rebooted from a bugcheck. The bugcheck was: 0x0000007f (0x0000000000000008, 0xfffff8037e4bae70, 0xfffff5023d960f00, 0xfffff803802546d9).

For what it’s worth, I am on windows 11, not 10. I doubt that’s the issue, though.
If I boot do the same crash scenario using AM2 or ACC, no crash. It only crashes with iRacing. I am using the 360hz FFB mode. I don’t know if this is the cause.

Bugcheck Analysis * -

UNEXPECTED_KERNEL_MODE_TRAP (7f)
This means a trap occurred in kernel mode, and it’s a trap of a kind
that the kernel isn’t allowed to have/catch (bound trap) or that
is always instant death (double fault). The first number in the
BugCheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a portion of those codes:
If kv shows a taskGate
use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
use .trap on that value
Else
.trap on the appropriate frame will show where the trap was taken
(on x86, this will be the ebp that goes with the procedure KiTrap)
Endif
kb will then show the corrected stack.
