GeneratedAppGlideModuleImpl is implemented incorrectly

This error is a big mess,
Its 2021 and it is still there, I just migrated to **Android X**

_**`Caused by: java.lang.IllegalStateException: GeneratedAppGlideModuleImpl is implemented incorrectly. If you've manually implemented this class, remove your implementation. The Annotation processor will generate a correct implementation.`**_

I 've added in my **build.gradle**
```
implementation 'com.github.bumptech.glide:glide:4.12.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.12.0'
```

Also in my **proguard** file

```
-keep public class * implements com.bumptech.glide.module.GlideModule
-keep public class * extends com.bumptech.glide.module.AppGlideModule
-keep public enum com.bumptech.glide.load.ImageHeaderParser$** {
**[] $VALUES;
public *;
}
```

I even tried deleted the whole progurd file still the same error,

Now I am thinking of migrating the entire project to **Picasso**
