acquireTokenSilent fails to return or throw an exception. (when used in Coil's ImageRequest).

Describe the bug I need to load an image that requires a Bearer token as a request header. When I try to retrieve the token from MSAL, the call never returns, and does not throw an exception either. This forces me to cache the token in my app, and used a cached, possibly expired token when I request the image.

Smartphone (please complete the following information):

I don't think any of these parameters matter, but I tested on:

Device: Pixel Fold and Pixel 6 Pro
Android Version: Android 13, TQ3C.230805.001.B2 and TQ3A.230805.001
Browser Chrome
MSAL Version 4.7.0

Stacktrace Application Not Responding error happens.

To Reproduce Steps to reproduce the behavior:

Have an AsyncImage in your Jetpack Compose layout:

                AsyncImage(
                    model = ImageRequest.Builder(LocalContext.current)
                        .data(imageUrl)
                        .crossfade(true)
                        .setHeader("authorization", "Bearer ${MSALAuth.getToken(LocalContext.current)}")    //If you delete this line, the call will complete successfully.
                        .build(),
                    contentDescription = "Test",
                    contentScale = ContentScale.Crop,
                    modifier = Modifier.clip(CircleShape)
                )

The MSALAuth.getToken() method is:

fun getToken(context: Context): String {
            try {
                println("Getting Token from MSAL")
                if (account == null) {
                    singleAccountApp =
                        PublicClientApplication.createSingleAccountPublicClientApplication(
                            context,
                            R.raw.msal
                        )
                    val acctResult = singleAccountApp.currentAccount
                    account = acctResult?.currentAccount
                }
                println("About to get token silently.") //. This is the last line that prints out, then application hangs here.
                val authResult = singleAccountApp.acquireTokenSilent(
                    getTokenParams(TOKEN_SCOPE)
                )!!
                println("MSAL Token retrieved.")
                return authResult.accessToken
            } catch (exception: Exception) {
                println(exception.localizedMessage)
                exception.printStackTrace()
                return ""
            }
        }

If related to user experience, use the format:

Go to '...'
Click on '....'
Scroll down to '....'
See error

If related to development, please provide relevant configuration details necessary to understand your problem including any relevant traces, logs, or otherwise.

Expected behavior A token should be returned, or exception thrown if interactive auth is required.

Actual Behavior The application will get a not responding error.

Screenshots If applicable, add screenshots to help explain your problem.
