[pstricks] pstricks and xelatex after recent update

[Luis Fernando Sequeira]

Compiling with xelatex:

I got a nice tree with texlive 2020.

PSTricks' v2.97  <2019/05/11> (tvz,hv)


I have just installed texlive 2021, and the lines connecting the root to the leaves do not display.

`PSTricks' v3.01  <2020/09/18> (tvz,hv)

This is the errors that I get:
