Pretty extensive for a trial but you could try this:
It is something on the PC that is causing Fences to be unhappy. The error you posted is something we see where Forcepoint is being used - usually in a corp environment but could be other AV software products. It could also be a windows shell extension (Fences runs in the Windows Explorer process) that is causing an issue.
In any case, a clean boot, under a different account, could help determine that.
