I think I got a clue,I installed clean windows 11,I did not establish an internet connection and did not install windows update. I installed the drivers manually from the dell site, (I only downloaded the drivers for the video cards from their site, which is compatible with windows 11) The problem starts when I install the Intel Integrated Sensor Hub Driver for hardware ID pci/ven_8086&dev_9dfc&subsys_08a71028&rev_30. Most likely the problem will be fixed when the driver set is updated. Before I came to this conclusion, I had the same problem in the scenario where I installed the drivers directly via windows update (Intel Sensor Hub) with windows update turned on.
I'm having a issue to upgrade/clean install W11 on my Vostro 5481. Clean install or upgrade from W10, the problem is the same: Black screen with cursor on login screen. Can't do any action, it's just "stuck". Already tried to disable all MS services and apps, and the graphics drivers as well, but the problem persists. Only works on the "first" boot. After the drivers complete installing, the bug appears. W8ing Dell support pronunciation about this issue.
