Classic Pets/Skeletons Issue

[Buffet]

Trying to convert the Pets/Skeletons with the Log-In menu option but unfortunately my native desktop resolution is not on the prompted list immediately after I uncheck the pet options.

When I pick an unnative resolution EQ immediately crashes when I launch the game.

Does anyone know a method to manually delete the new pet model files so it defaults to the older versions?

Thanks in advance for any feedback
