PySide 5.15 is compatible with Python 2.7, and 3.5+
so it would be better for you to file a bug report,
and communicate the error so it can be solved or workaround.
Keep in mind that PySide was officially released in 5.12,
so on paper, you can take that as the initial stable version.
The path from there on was mainly to catch with missing API
and properly handling of Python's GIL,
so I would *highly recommend* you use 5.15.x

If PySide 5.11 is installed...
was that built? or installed via pip?
it seems risky to play with that, but if it works at the moment,
and you cannot fix your build problems, I guess you can keep doing it,
but as mentioned before, there were some major issues that we fix in
5.14.2, and are included in the following versions.
We usually recommend people to use the same Qt and PySide versions,
because at least with that we guarantee there will be no issues.
