The BSOD Doctor
There's no evidence of a BSOD in the System log and no dump either, although there is a dump write failure message...
Code: 
Log Name:      System
Source:        volmgr
Date:          15/07/2024 18:30:41
Event ID:      161
Task Category: None
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      Martins_Laptop
Description:
Dump file creation failed due to error during dump creation.
When a BSOD occurs a BSOD error is written to the System log, so the absence of one is firm proof that this wasn't a full BSOD but some other type of failure.

Even though I don't think the failure you had was a BSOD, in order for dumps to be written in the future all of the following must be true...
  • The page file must be on the same drive as your operating system
  • Set page file to "system managed"
  • Set system crash/recovery options to "Automatic memory dump"
  • Overwrite any existing file box must be checked
  • The dump file location must be %SystemRoot%\MEMORY.DMP
  • Windows Error Reporting (WER) system service should be set to MANUAL
  • User account control must be running
In addition, the following can also prevent you seeing dumps...
  • SSD drives with older firmware do not create dumps (update the drive firmware)
  • Cleaner applications like Ccleaner delete dump files, so don't run them until you are fixed
  • Bad RAM may prevent the data from being saved and written to a file on reboot, so if all else fails test your RAM
I do see the the kernel error 41 message, and there's only one of those in the System log too, which does indicate that the system didn't shutdown properly. Generally, when you see these with no BSOD error message it's because the hardware failed underneath Windows preventing the kernel from catching the error and BSODing.

The only error message of note in your System log is a WHEA corrected hardware error message for your PCIe root port...

Description:
A corrected hardware error has occurred.

Component: PCI Express Root Port
Error Source: Advanced Error Reporting (PCI Express)

Primary Bus:Device:Function: 0x0:0x1D:0x0
Secondary Bus:Device:Function: 0x0:0x0:0x0
Primary Device Name:PCI\VEN_8086&DEV_06B0&SUBSYS_86681558&REV_F0
Secondary Device Name:
This is the last logged message before we see the system restart messages and so is most likely the cause of whatever failure you had. Note that the times shown in the event viewer are local to whoever is viewing the log, so that 18:06 time (my time) was actually 16:06 your time. The very next message is logged at 18:30 (16:30 your time) and that's the first message of the reboot.

There are no other errors in either the System or Application logs that offer any insight, and there is also only that one WHEA error. Without a dump we really don't have much to go on. I'd be pretty confident that the corrected hardware error for the PCIe root port was involved, though when we see this it's usually a PCIe device rather than the port that has had a problem.

I wish I could be more detailed or specific but there is no other data that helps. It could of course have just been a glitch.
