While I confirm that using the Manifest you provided the example works, using the latest version with your patch I have the same error:
using Pkg
cd(@__DIR__)
Pkg.activate(".")
Pkg.add(["Interact","Mux","Plots"])
Pkg.add(url="https://github.com/mkitti/WebIO.jl.git#mkitti-fix-mux-integration")
using Interact, Plots, Mux
mp = @manipulate throttle=.05 for λ=0:.1:5, μ=0:.1:5
xs = range(0.0, 1.0, length = 100)
Plots.plot(xs, x -> λ*x^2 + μ)
end
ui = dom"div"(mp)
WebIO.webio_serve(page("/", req -> ui), 8003)

I saw a few cool html generators that could be combined with Oxygen and I think it was HTMX.jl but I might be mistaken. See the following discussion
