False positive: Incompatible types in capture pattern (pattern captures type "Exception", variable has type <deleted>)

Bug Report
When trying to use a match pattern and bind to a variable with the same name as an except ... as bind, mypy starts returning an error.
If I remove the try/except block or don't try to attempt to reassign the variable, the issue goes away.

I've tried to search for other similar issues, but couldn't find much. Hope it's not a duplicate.

To Reproduce

def main() -> None:
    try:
        pass
    except Exception as exc:
        print(exc)

    result = Exception()  # this could for example be the result of `asyncio.gather(..., return_exceptions=True)`
    match result:
        case Exception() as exc:
            print("got exception", exc)
        case _:
            print("got something else", result)


main()

Playground URL: https://mypy-play.net/?mypy=master&python=3.13&gist=4d9bc9f42141eb6093823efcbc0dafd7&flags=allow-redefinition
Tried with various versions of mypy (1.8.0, 1.15.0, master) and Python (3.10, 3.11, 3.13).
Tried with --allow-redefinition and without.

Expected Behavior

No error from mypy, at least when using --allow-redefinition.

Actual Behavior

main.py:9: error: Incompatible types in capture pattern (pattern captures type "Exception", variable has type <deleted>)  [misc]
main.py:10: error: Trying to read deleted variable "exc"  [misc]
Found 2 errors in 1 file (checked 1 source file)

Your Environment

• Mypy version used: 1.8.0, 1.15.0, master
• Mypy command-line flags: --allow-redefinition
• Mypy configuration options from mypy.ini (and other config files): N/A
• Python version used: 3.10, 3.11, 3.13

Start with the main.py reproduction and run mypy with and without --allow-redefinition. Trace the interaction between the except ... as binding and the later match capture pattern for exc. Done means the reproduction no longer reports the incompatible capture or deleted-variable errors, with regression coverage for the case.
