How do you fix the "Unsupported Pixel Type" error when running the Flow Direction tool while using "MFD" as your flow direction type?

Here are all the messages that I got from my execution of Flow Direction, trying to use the new Multi Flow Direction algorithm in ArcGIS 10.6.

I've ran the tool on multiple DEMs, and none have worked. The only tool I've run on the DEM before this is running Fill on it. I haven't seen anyone else have a problem with it, though that makes sense given how new it is. If anyone has advice for how to fix this, I'd appreciate it.
