I am on Win10 Pro with all updates (Version 1909, OS Build 18363.720). I am also using the latest RAMDisk v2.03.00.
When PC boots up, login screen appears for a fraction of second, and then I am getting BSOD (in other words, it happens before log in). The system eventually boots up after 3-5 attempts. Exception occurs in asramdisk.sys. Below are some details from dump file:
Exception:
