Lenovo 15ARE05 - RTC timer, stuck on boot, BlInitializeLibrary Failed - Bios Request

[CrisPell]

I became unfortunate owner of used Lenovo 15ARE05 which is absolutety amazing by it's specification for general purpose, but weirdly after some time noticed some problems with working on it. And I'm think that is BIOS/UEFI related issue.

I made at first day a BIOS upgrade... maybe a huge mistake to available on page E7CN51WW.

Every few minutes my clock just went's off his sync with other devices.
Not every time boots after restart or from sleep.
Gets error BlInitlializeLibrary Failed 0xc0000185

Is it possible to you to prepare a new fresh copy of BIOS if I provide informations? I have CH341A programmer.
