Here's a firestorm of uncommon ferocity in the CE industry.
The short version is that devices that use uncompressed video (the latest and greatest XBox, PS5, nVIDIA 3000 series display cards) can't be passed through by any of the HDMI 2.1 "capable" Denon, Marantz and Yamaha AVRs.
The rumor is that the PS5 may be able to send compressed video but otherwise, gamers will need to plug their consoles/computers directly into the TV and use ARC for sound.
Those who thought they could avoid CEC are in for a battle as ARC usually requires it to be enabled.
Speculation is that this problem may not be solved (other than using a direct-to-TV connection or reducing frame rate) until 2022.
Bug in HDMI 2.1 chips Affect AV Receivers, XBOX Series X & NVIDIA Graphic Cards
Certain HDMI 2.1 AV receivers from Denon, Marantz and Yamaha have a bug in their HDMI 2.1 chipsets that causes blank screen for 4k/120Hz & 8k/60Hz resolutions. Sound United gives work around and promises future fix.
