Having trouble installing vscode-python, using OSS on arch-based linux.

[LunarPidgeon]

I am using OSS version 1.90.0 (latest at time of writing) on EndeavourOS, which is arch-based. When I attempt to do anything that 'wakes' the ms-python extension (such as creating a new .py file or loading the extension's welcome page), there is a message that never goes away which says "Python extension loading...", and an error which reads "Extension activation failed, run the 'Developer: Toggle Developer Tools' command for more information". Opening the dev console reveals the following error:

Activating extension 'ms-python.python' failed: Extension 'ms-python.python' CANNOT use API proposal: terminalShellIntegration.
Its package.json#enabledApiProposals-property declares: codeActionAI, contribEditorContentMenu, quickPickSortByLabel, portsAttributes, testObserver, quickPickItemTooltip, terminalDataWriteEvent, terminalExecuteCommandEvent, contribIssueReporter, notebookVariableProvider but NOT terminalShellIntegration.
 The missing proposal MUST be added and you must start in extension development mode or use the following command line switch: --enable-proposed-api ms-python.python.

I have tried adding "enable-proposed-api": ["ms-python.python"] to argv.json, but it did not work. Disabling telemetry in settings did not work. Disabling terminal shell integration also did not work. How can I get this set up properly?

I worked around this by installing the visual-studio-code-bin package from the arch repository and building from source, so it seems to be an issue specifically with the OSS package. I will attempt to find their page and report the issue to them.
