Python 3.6 can work well on old version of MacOS. When I upgrade MacOS to the latest version Big Sur 11.2.3. Python 3.6 fails to start and crashes. Python 3.7, 3.8, 3.9 can perform well on the new version MacOS Big Sur 11.2.3. The crash information attached as follows:

I'm sorry you ran into this but, unfortunately, the binaries from Python.org macOS installers prior to 3.7 do not work on macOS 11 Big Sur. Since Python 3.6 and 3.7 are in the security-fix-only phase of the life cycles, we do not provide support on them for new OS versions and providing new binary installers. Please see the detailed response to bpo-43470 for more information.
