Avatar unable to attack or left-click use items

[Celarious]

My main avatar at ID YQC seemingly lost the ability to attack or use items with left-click at some point. It used to be able to, as I placed a flag and attacked a bunch when I first started the empire. I have checked that all of the binds are default, which they are. 

I tested with a new avatar on the same save, and that one worked fine. It could attack as normal. As a result, I think some form of avatar corruption may have happened on the main one. I can provide the save if needed

I have had the exact same problem, my character completely lost the ability to use items in any way.
A new character in the same universe worked normally.
