Try the following patch.
If it works I will commit it to main.
FWIW I have never found such errors, even although I was aware of the reason.
The issue is that the f-strings (*f* standing for format) had their own python
parser. This parser was different from the main parser. In this case we have hit
a limitation of the parser until Python 3.12.
The fix is quite simple, evaluate the expression outside of the formatted string
and it works.
Best regards,
