I just received a Crucial Pro DDR5-6000 32GB kit with two 16GB UDIMMs, rated at CL36 for gaming. The packaging mentions support for Ryzen 9000-series processors, and Crucial's compatibility tool doesn't show my motherboard as supported. Will this memory work properly with my Ryzen 7 7800X3D, or could there be compatibility or warranty issues if I enable AMD EXPO?

It should work fine. DDR5 memory isn’t restricted to one specific Ryzen generation, and the Ryzen 7 7800X3D supports DDR5. The Ryzen 9000 wording is likely a platform label or marketing qualification, not an indication that older CPUs cannot use the kit.
Compatibility lists usually only include hardware that was tested by the manufacturer, so they aren’t complete. You may need to enable the AMD EXPO profile manually in the BIOS to run the memory at 6000 MT/s; otherwise it will use a slower default speed.
There shouldn’t be a warranty problem simply because you enable EXPO on a board that wasn’t listed in the compatibility tool. EXPO is a normal memory profile, though—as with any overclocking feature—stability depends on the motherboard, BIOS, CPU’s memory controller, and the kit. If it isn’t stable, lower the speed or adjust the settings.
