The problem in that dump appears to be with the Nvidia driver nvpcf.sys, which is part of the Nvidia graphcis driver package. It unloaded without closing the resources it had open...
Code:
IP_MODULE_UNLOADED:
nvpcf.sys+1d7d0
fffff807`19a7d7d0 ?? ???
That's why you got the DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS BSOD.
Laptops often use customised graphics drivers, both for the dGPU and the iGPU - which work hand-in-hand in a laptop. The generic drivers from Nvidia and Intel don't contain these customisations and often cause problems on laptops.
I suggest that you uninstall the current graphics drivers, using Device Manager for the Intel graphics driver and
DDU for the Nvidia graphics driver, and then download and install the Intel and Nvidia graphics drivers from the
Acer website for your AN515-56 laptop. They are dated 2021 but we know for certain that they are fully compatible with each other and with your laptop.
If it BSODs on these drivers please run the SysnativeBSODCollectionApp again and upload the resulting zip file.
BTW. I also note that you're running with mismatched RAM sticks. One is a Crucial CT8G4SFRA32A.M4FF and the other is a Micron 4ATF1G64HZ-3G2E1. RAM should only be bought in packs of matched sticks to ensure that all the timings align. I don't believe that this is related to your current problem, and you may have got away with this mismatch so far, but just be aware that it may come back to bite you in the future.
