Python version 3.12rc1 - cannot find backend (Windows 11) and fatal exception in set

1. keyring list-backends gives nothing when installed on a Python 3.12-rc1 virtual environment.
2. calling get_password cause an exit from the Python interpreter

they work perfectly under Python 3.8.10 with previous and the latest versions of keyring

o/s is Microsoft Window 11 pro (10.0.22621) and I am *NOT* working in a VM or Linux just a command shell
I am not running with admin privs

having just hound the Python -X faulthandler option I get this when running a trivial set and get program, the fault happening in the set call.

```
(z312) C:\Users\****************\Python\z312>py -X faulthandler ..\zzzz\test_keyring.py
Starting....
Windows fatal exception: access violation

Current thread 0x000055c4 (most recent call first):
Windows fatal exception: access violation

````

The trivial code is

```python
import keyring
print( 'Starting....' , flush=True )
keyring.set_password("mySystem", "myUsername", "S3CR3T_P455W0RD")
print( 'password should be set' , flush=True )
saved_password = keyring.get_password("system", "myUsername")
print( f'{saved_password=} which I believe is a generic password set above ' )
```

Start with the shown Python 3.12-rc1 Windows command and the trivial test_keyring.py program, using -X faulthandler to reproduce the access violation. Compare keyring list-backends and the set_password/get_password calls with the reported Python 3.8.10 behavior; done means the backend is found and the sample completes without an interpreter crash.
