iMac Big Sur restarted more than three times a day
fellow apple users, I have a serious situation in my iMac mid-2015 upgraded with Big Sur. It restarted more than three times a day with error message "your computer was restarted because of a problem". Background: I upgraded this iMac with WD_BLACK 1TB SN750 NVMe (WDS100T3X0C-00SJG0) via an interface "M.2 PCIE NVME SSD Adapter Converter". I totally removed the original hard drive and cable. It works great in the first three months. Recently, it begins to restart unexpected more than three times a day. The problem details varies and the most recent one is as following.
Can anyone show me how to resolve this problem? I assume it was because of the SSD and adapter. Any way to resolve it without changing the SSD again?
