The issue you are experiencing with the Right Alt + Shift shortcut failing to switch input from Arabic to English may be related to how the Right Alt key is interpreted in the Arabic layout. In many cases, the Right Alt key (also known as AltGr) can conflict with standard Alt key functions, which might explain why it only works in one direction (English to Arabic) and not the other.
This behavior is known, and users have reported similar issues where the input method editor (IME) does not switch correctly between languages when using certain key combinations. Unfortunately, there isn't a specific workaround mentioned in the provided context to force the Arabic layout to recognize the Right Alt as a standard Alt key.
You may want to try using the standard Left Alt + Shift combination to switch between languages, as it might not have the same conflict as the Right Alt key. Additionally, ensure that your system is fully updated, as updates can sometimes resolve these types of issues.
If the problem persists, consider checking for any known issues related to input methods in your version of Windows, as these can vary with updates.
