I use Libreelec on an rpi4b.
Yesterday I did the proposed update to 10.0.2 and since then the 3840x2160 24p video no longer switches to 24p but stay in 50p. In 1080p no problem, the tv goes well in 1080p24. Did you have the same problem or do you have a solution please?
I posted on another topic but got no response.
