Fatal error in launcher: Unable to create process using '"'

Without further ado, just execute:

python -m pip install --upgrade --force-reinstall pip

Some blog posts on the Internet just give the upgrade command to rebuild the dependencies of pip and python. At this time, if your pip itself is the latest version, then you will hate this blog post that can solve the problem, because it can't solve your problem. .

Just use force-reinstall to force pip to be reinstalled with the current python runtime.
