I have an issue whereby my laptop randomly turns my screen off or logs me out. From /var/log/auth.log it seems that the system thinks the lid is closed:

Timeline of events:
-09:36:44 I manually rebooted the system
-09:40:15 First event where laptop screen goes black and/ore logs me out
-09:40-09:45 A series of 'crashes' where I am logged out and the system log seems to think the laptop lid is shut. I did not physically move the lid during this period.
Can anyone spot something from this log that could be causing the issue? Or things I could do to investigate further?
System:
-Ubuntu 20.04.3 LTS, 5.11.0-34-generic (also happened with kernal at least as early as 5.11.0-27)
-Dell Latitude 7280
Other observations: Happens regardless of whether charging or not. Seems to happen more often while typing, versus using mouse.
