ok, there was an upgrade in OSGeo4W to python 3.7.6 recently, maybe it's now related to

ctypesgen/ctypesgen#77 (comment)

In Python 3.7.6 - 3.8.1 ctypes is broken if unpatched.
In Fedora, the fix of the upcoming 3.8.2 has recently been backported [1]. But it requires the recompilation of Python.

The easiest is to downgrade the Python version.

Is this still an issue? AFAIK the solution is to use the right Python version.

To which version?

To which version?

• on Fedora 31 I have Python 3.7.7 (I assume patched or the "pure" upstream version) which works fine.
• on Alpine based docker images we use Python 3.8.2 successfully.

Originally reported problem should be fixed in OSGeo4W. @hellik Can we close?

closing as fixed in OSGeo4W by downgrading python version. in the long term, upgrade python >= 3.8.2
