Canon has removed the firmware v1.2.0 download for the Canon EOS R3 due to a bug in the software.

The bug is described on the DPReview Forum

The issue is that if you have v1.2 on your camera and then perform a reset the mode dial does not work correctly and you cannot change between Tv Av etc

If you have updated to firmware v1.2.0 for the Canon EOS R3, do not do any resets until v1.2.1 is released.

Canon has always fixed these sorts of firmware bugs pretty quickly, so I would expect an update very soon.
