pFq Not compatible with TaylorSeries package

I tried to use HypergeometricFunctions and TaylorSeries at the same time as follows.

using HypergeometricFunctions
using Plots
using TaylorSeries
x = set_variables("x", order=100)[1];
Base.isless(y::Number, x::TaylorN) = isless(y, x.coeffs[1].coeffs[1])
Base.log1p(x::TaylorN) = log(1+x)
Base.eps(::Type{TaylorN{T}}) where T = eps(T)
Base.isless(x::TaylorN, y::Number) = isless(x.coeffs[1].coeffs[1], y)
HypergeometricFunctions.pFq((2.0,),(5.0,),x)

However, I got the error:
ERROR: MethodError: no method matching AbstractFloat(::TaylorN{Float64})

Closest candidates are:
(::Type{T})(::T) where T<:Number
@ Core boot.jl:792
(::Type{T})(::AbstractChar) where T<:Union{AbstractChar, Number}
@ Base char.jl:50
(::Type{T})(::Base.TwicePrecision) where T<:Number
@ Base twiceprecision.jl:266
