I have two “modern” computers:

11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz, 65,259 MB RAM

Intel(R) Core(TM) Ultra 9 285H, 65,083 MB RAM

The first one accepts the installation of Vegas 20.0 and 23.0 in FRENCH.
The second one does NOT!
I have to install the English version…
Yet it is the same installer!
Why?
