We haven’t seen this issue after 42 BIOS version update; just to narrow down the issue:
Could you please attach the result of the Intel® System Support Utility? Also let’s try to test your system with the Intel® Processor Diagnostic Tool, to verify the functionality of your system. The diagnostic checks for brand identification, verifies the processor operating frequency, tests specific processor features, and performs a stress test on the processor.
Could you please attach the results to your answer?

Would you let me know if the issue comes up again?
