[Python] Visual Studio Enterprise 2019 IntelliSense false positives with Python 3.12, fine...

I have a VS2019 solution with Python projects running on Windows 10. I recently installed Python from 3.12 to upgrade from 3.8. Now I can select either 3.8 or 3.12 in the drop-down menu in my VS2019 toolbar and debug with either one. The programs run properly with either version, but IntelliSense flags a whole bunch of errors in 3.12 that seem like perfectly valid code. When I switch back to 3.8, IntelliSense has no problem with these lines. Here's a brand new project I created in this solution showing an example of this:

In case the screenshot doesn't come through, here's the actual code:

ns_proc_prefix_char = 'C'
ns_sb_procs = {'src_amon':f'${ns_proc_prefix_char}MDMN',
'src_coll':f'${ns_proc_prefix_char}MDCC'
}
print(ns_sb_procs)


In my VS2019 environment, there are IntelliSense errors under the whole quoted value (including quotes) for the f-strings. When I mouse over them, it just says "invalid syntax". I tried rebooting my system and updating VS2019, but these flagged errors aren't going away.

I doubt this is related, but I wanted to share it just in case. When debugging with Python 3.12, it logs this warning at startup:

This version of python seems to be incorrectly compiled
(internal generated filenames are not absolute).
This may make the debugger miss breakpoints.

This is the latest Python 3.12.10 install for Windows that I got directly from Python.org. I was able to add "-Xfrozen_modules=off" to the Interpreter Arguments section of the debug settings to stop that message.
