Unresolved reference 'match' - Python Version 3.11.1

I wanted to use the new 'match-case' statement added in python 3.10 (previously installed 3.8) so i installed it and added a new interpreter in the settings.

The match-case statement does work now, but i still get all of it flagged in PyCharm.

Simple code example from stackoverflow for testing purposes and added version check.
Version is '3.11.1 (tags/v3.11.1:a7a450f, Dec  6 2022, 19:58:39)'

Is there any fix for this?

from sys import version
print('version =', version)
def f(x):
    match x:
        case 'a':
            return 1
        case 'b':
            return 2
        case _:
            return 3
print(f('c'))
