Hi KMcHattie,
Please confirm with us that what happened before this issue occurred.
Since these raw files worked before, what operations make them not work is worth to be attended.
It’s convenient to use the following tool to fix firstly.

If this tool doesn’t work, I advise you to refer to this page below, it shows a similar situation as you.

We could try to change the “photowiz.dll” to see whether it can solve the problem, refer to the solution which are provided by
matabanadzo.
What’s more,
let’s use process monitor to capture the trace when this issue occurs, and see which files and driver is related. We can get this tool from the web page below.
