Compressor Droplets have stopped functioning.

Recently all of my Droplets for Compressor 3.5.3 have stopped working.

Icons have changed to developer icons as well.

Dragging source videos does nothing, opening the droplet says that it is Damaged or Incomplete.

I tried restoring the same droplets from a Time Machine backup from when they were working, but that has not changed my situation.

Creating new Droplets in Compressor also does nothing.

Compressor Repair has also not helped.

Repairing disk permissions did nothing.

Any ideas?
