Hello,

Can you try to use a newer libclang?
There are some pre-built packages on
http://download.qt.io/development_releases/prebuilt/libclang/
that you can unzip, then point the LLVM_INSTALL_DIR
variable to the directory.

Some people reported issues with 5.15 and libclang<=8
in other communication platforms, so it might be that.


On a side note, I really recommend you to try to move
away from Python 2, since as you might know,
it was deprecated [1], and we are completing removing
Python 2 support for Qt 6.

Cheers
