Probably you are using an old dvipdfmx.cfg.
Or using an old Ghostscript in which NOSAFER is the default.
For the new one in TL2021 pretest, with gs-9.53.3, where SAFER mode
is the default, I can confirm on W32:

xdvipdfmx TransparencyTest.xdv
Error: /invalidfileaccess in --run--

Apparently it is needed to read pstricks.pro given by fullpath,
that is impossible in SAFER mode.

If I use the new additional dvipdfmx-unsafe.cfg:

xdvipdfmx -i dvipdfmx-unsafe.cfg TransparencyTest.xdv
    **** WARNING: .setopacityalpha is deprecated (as of 9.53.0) and will be removed in a future release
    **** See .setfillconstantalpha/.setalphaisshape for the improved solution
    **** WARNING: .setopacityalpha is deprecated (as of 9.53.0) and will be removed in a future release
    **** See .setfillconstantalpha/.setalphaisshape for the improved solution

The resulting TransparencyTest.pdf is fine.

Thanks,
Akira
