ANR during RequestManager Initialization

We are encountering an ANR which appears to occur when Glide.with() is used to load images, with the stack trace pointing to delays during RequestManager initialization and decoding.

Here’s a relevant portion of the stack trace:

```main (runnable):tid=1 systid=13565
at com.bumptech.glide.request.RequestOptions.decodeTypeOf(RequestOptions.java:213)
at com.bumptech.glide.RequestManager.(RequestManager.java:59)
at com.bumptech.glide.GeneratedRequestManagerFactory.build(GeneratedRequestManagerFactory.java:18)
at com.bumptech.glide.manager.LifecycleRequestManagerRetriever.getOrCreate(LifecycleRequestManagerRetriever.java:43)
at com.bumptech.glide.manager.RequestManagerRetriever.get(RequestManagerRetriever.java:158)
at com.bumptech.glide.Glide.with(Glide.java:540)
...
```

The ANR happens during image loading, likely due to some operations such as decoding or request initialization being performed on the main thread.

**Glide Version**: 4.15.1

**Integration libraries**: No

**Device/Android Version**: Based on Firebase Crashlytics data, the ANR occurs on multiple devices, with a significant number of occurrences on Oppo devices running Android 11.

**Glide load line / `GlideModule` (if any) / list Adapter code (if any)**:
We have a helper function that is called from a fragment to load a profile image.

```kotlin
fun loadImageWithScopedContext(
context: Context,
imageView: ImageView,
photoUrl: String?,
@DrawableRes placeholder: Int
) {
if (isEmpty(photoUrl)) return

Glide.with(context)
.load(photoUrl)
.dontAnimate()
.diskCacheStrategy(DiskCacheStrategy.ALL)
.placeholder(placeholder)
.into(imageView)
}

```

**Layout XML**:
```xml

```
