Hi,
This is latest Win10 OS build version (19042.685). So it may be related to the driver or some files crash the system.
Check event log to find if any error you could find.
For this issue, you need to check to see if your PC is producing any minidump files. They provide any insight into a potential cause of the system crashes.
Open Windows File Explorer
Navigate to C:\Windows\Minidump or Memorydump.
