P: (Win/Mac) Lightroom Classic 12.0 Unable to export: Watermarking Failed

@Fabio TK: "I tried to cancel, replace, modify, create an empty/fake watermark, nothing works"

Did you try moving all the watermark presets out of the settings folder and resetting LR's preferences, as described here?

@gowthampannala: "it's crashing i.e closes LR window completely not an error dialog box".

Hmm, unfortunately, that's the first instance of a crash reported here. 

"I have tried all the steps outlined in this post"

There are many different workarounds posted here.  Did you try resetting LR's preferences and moving all watermark presets out of the settings folder, as described here:

Hallo,

nach dem neuesten Update 12.0 auf kann ich leider keine Bilder mehr exportieren, egal welches Format. Hier wird mir dann ein Fenster angezeigt wo steht, Export nicht möglich: Wasserzeichenmarkierung fehlgeschlagen.

Leider verwende ich kein Wasserzeichen, auch wenn ich dort ein Häckchen setzen würde, geht es nicht.

Hat jemand hierzu eine Idee?

Ich verwende einen MAC Monterey Version 12.6.

I have the same issue after updating LRC CC to V12 catalogue, I tried to cancel, replace, modify, create an empty/fake watermark, nothing works, the reply is always the same and I can't export my photos . I'm using Mac OS Big Sur

I tried these two things suggested by AE here and it didn't work, so I created a new watermark and made it invisible by the opacity option, it worked so when I went to export again I unchecked the box and it works just fine.
