Cython 0.29.33-1 :error update

Impossible to update cython 2 : a message " error happends in the build " , " error in the construction cython 2" and all is stopped. ( Error during yay -Syu)
Note : my system is updated regularly - one / week - and I use python 3 ; also cython 2 works as it’s…
Also since 3 months I do not update python2 as I understood it’s no more maintained?
If you have any idea .

Can you share the full output from yay?

here the outlet :
