PNG format is not supported in Bridge 13.0.3.693

Hi, @inave 

I know this is no consolation, but it works on my system. Does this happen on all folders or only on certain folders? Regardless, the first thing I'd check is to purge the cache for that folder. [Tools (menu) -> Cache -> Purge the cache for XX folder]

If that doesn't work, please try to rebuild the settings for Bridge

Quit Bridge (if running). Just before clicking on Bridge in the Dock or double-clicking the application for the Mac, press Command-Option-Shift. For PCs, press Control-Alt-Shift. Then open Bridge BUT KEEP your fingers on those keys until you see a window pop up. From the window, choose “Reset Preferences," "Entire Thumbnail Cache,” and/or "Reset Standard Workspaces.” In your case, choose "Reset Preferences."

Please let us know if either of these resolves the issue
