Randomly hanging screen during computer startup

Hello,
I have problem with randomly hanging screen when I startup my computer. I see grub screen then system loading stucks on blinking underscore and I have to restart computer multiple times before I be able get in to login screen.
I’m using thinkpad t495s and GNOME, after installation I had problem with Failer to start Load/save screen backlight brightness of backlight: acpi_video0 so I used systemctl mask systemd-backlight@backlight:acpi_video0.service maybe its something related with this?

Hello @gostop

Have you tried adding Slice=-.slice to /usr/lib/systemd/user/gnome-session-restart-dbus.service as root to the end of it.

I didn’t edit this file before but I just checked and Slice=-.slice already exists there.
