[issue42446] Assertion error os.path.exists(pyc_path) while building Python 3.8.6 with-ensurepip

[Thoradia Quack]

New submission from Thoradia Quack <thoradia.quack at gmail.com>:

I try building Python 3.8.6 with-ensurepip (see configuration below) but this fails with an assertion error (see error below).

I do not understand the error and I do not know how to fix it.

For what it is worth, I used to successfully build Python 3.8.5 with the same configuration.

Thank you for any help with this.

Configuration:
