Getting Unable to parse input: "Parse error" when running bat <file>

[TDH55]

Hi, I've been using bat for a couple of years now and have recently started getting a Unable to parse input: "Parse errror" response when trying to use bat to view files. This seems to be happening with all file types, I've generated a new config file as well as uninstalling and reinstalling bat but haven't had any lucky finding a fix. Has anyone else had this happen or have any ideas what may be going on?
