Unresolved name causes "Failed to produce diagnostic for expression..." error

[samrshi]

Describe the bug
Earlier, I was refactoring some code and was in the process of changing the name of a variable for a dictionary. Before I changed one of the references to the variable, I received the following error message:

Failed to produce diagnostic for expression; please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the project

I sometimes also see a Cannot find '<#name#>' in scope error, but inconsistently between environments. The error could be resolved by changing the expression to use the updated name, but for a moment I was concerned I had a much more complicated error.

Steps To Reproduce

1. Paste the following code into Xcode or an Xcode Playground (possibly only using Xcode 14 beta 3/the version of Swift it runs).
2. Attempt to build (or run in an Xcode Playground).
3. Check for described error message.

var newName: [Int : [Int]] = [:]

for (key, values) in oldName {
    for (idx, value) in values.enumerated() {
        print(key, idx, value)
    }
}

...

Expected behavior
I expect to not see a Failed to produce diagnostic for expression error for a simple unresolved name error.

While I'd usually appreciate the help, I do not need any comments on Swift best practices or correctness as this happened while I was refactoring someone else's code to ensure that it produces the intended result, is more readable, etc. Thanks for wanting to help though!

Environment (please fill out the following information)

• OS: macOS 12.4
• Xcode: Version 14.0 beta 3 (14A5270f)

Additional Context:
Original-ish code snippet in plain-text. Notes:

• there is a function parameter called entityForRemoval of type Entity
• there is a class property called committedEntities (the correctName in the simplified version) of type [KeyType : [Entity]]
• changing entities to committedEntities resolves all errors

// Remove entity from parent and dictionary
entityForRemoval.removeFromParent()
for var (key, entitiesForKey) in entities {
    for (i, entity) in entitiesForKey.enumerated() {
        if (entity == entityForRemoval) {
            entitiesForKey.remove(at: i)
        }
    }
