Fix adding third party LUTS in Media Encoder. It does not work!
Checking the Lumetri Color/LUT box in Media Encoder, then clicking on Select in the dropdown menu followed by clicking on the desired Canon LUT does not work. The LUT box still says "none" and no LUT is applied. these Canon LUTS work fine in Premiere Pro, but there is a bug in Media Encoder and it needs to be fixed. At present I cannot apply a Canon LUT before encoding in Media Encoder.

I am having the EXACT same issue. Uninstalled/Reinstalled both programs. Need to apply LUT's to batch exports and this is driving me mental
