Describe the bug

black cannot format this type of code: f"{'\''}"

$ black foo.py
error: cannot format foo.py: Cannot parse: 1:3: EOF in multi-line string

Oh no! 💥 💔 💥
1 file failed to reformat.

I was thinking that it might be the same bug as #4334, but the example in that issue (f'{'a'}') doesn't produce an error in black 24.4.2 anymore, and Python 3.12.2 accepts the above code:

import ast
from pathlib import Path

print(f"{'a'}")
print(ast.parse(Path(__file__).read_text()))

$ python3 example.py 
a
<ast.Module object at 0x1014a9410>

To Reproduce

Playground

Expected behavior

I have no opinion on how this should be formatted. Leaving this code as it is would be fine.

Environment

$ black --version
