Exception in ChangeSignatureCodeRefactoringProvider after wrong automatic closing brace placement

[jhinder]

Version Used: VS 2022 17.4.0

Steps to Reproduce:

1. Place the cursor at the marked location
2. Insert {.
3. Press the Return key.

Note that the parentheses are balanced at the start.

namespace N;

internal class C
{
    private void M()
    {
        M1(x => M2("a", y => M3<int>(z => $$)));
    }

    private void M1(Action<object> a) { }

    private void M2(string a, Action<object> e) { }

    private void M3<T>(Action<T> a) { }
}

Expected Behavior:

1. The closing brace is placed at the correct location, forming an empty statement block:
   M1(x => M2("a", y => M3<int>(z => { })));
2. The refactoring does not crash due to the malformed syntax.

Actual Behavior:

1. The closing brace is placed between the second and third closing parenthesis, leading to malformed syntax: M1(x => M2("a", y => M3<int>(z => {))});
2. After pressing Return the ChangeSignatureCodeRefactoringProvider throws an exception, leading to a gold bar. The stack trace is posted below.

The second problem does not seem to occur when the namespace declaration is missing.

The faulty closing brace placement appears to be fixed in VS 17.5 Preview 1.
