The latest version of KNITRO.jl is 0.11.1 and was released 5 days ago. It works with Knitro (the solver, not the wrapper) 11, 12 and 13. Your first install is correct, and downgrade JuMP to 0.22.3 as KNITRO.jl does not support MOI 1.0 in the version 0.11.1. You can use KNITRO.jl#master if you have to use JuMP 0.23/MOI 1.0, and a new release of KNITRO.jl is expected soon.
