You're encountering a frustrating issue: UUID Magisk permission rejections and Shizuku/Zygisk Detach failing to gain app permission. This can significantly impact your device's functionality and customization options. While the specifics are unclear without more context, let's explore potential causes and solutions. It's important to note that Magisk permission management can be complex, especially with newer Android versions and security implementations.

**Understanding the Problem:**

UUID permissions are essential for Magisk modules to interact with system apps and components. For example, Shizuku and Zygisk Detach rely on these permissions to operate effectively. When these permissions are denied, modules can't access the required system functionality.

**Possible Causes:**

* **Android Version & Security Updates:** Newer Android versions often introduce stricter permission sandboxing, which can lead to more frequent permission rejections.
* **App Misconfiguration:** Incorrect settings within Shizuku or Zygisk Detach might be preventing them from requesting or managing permissions correctly.
* **Conflicting Modules:** An installed Magisk module might be interfering with the way Shizuku or Zygisk Detach function.
* **Device-Specific Issues:** Certain devices might have unique configurations or security settings that cause compatibility problems.

**Troubleshooting Steps:**

1. **Update Magisk and Modules:** Ensure you're running the latest version of Magisk and any relevant modules, including Shizuku and Zygisk Detach.
2. **Review App Permissions:** Check the permissions granted to Shizuku and Zygisk Detach within your device's settings. Make sure they have the necessary UUID-related permissions.
3. **Disable Conflicting Modules:** Temporarily disable other Magisk modules to see if they are causing the permission issues.
4. **Logcat Analysis:** As you suggested, providing a logcat can be incredibly helpful for diagnosing the root cause. Look for errors or warnings related to Magisk, UUID permissions, or Shizuku/Zygisk Detach.
5. **Consult Community Forums:** Engage with the Magisk and XDA Developers communities; they are excellent resources for troubleshooting complex issues.
6. **Factory Reset (Last Resort):** If none of the above steps resolve the problem, a factory reset might be necessary. However, back up your data before doing this.

Remember: Magisk is a powerful tool, but it requires careful configuration and troubleshooting. Be patient, methodical, and don't hesitate to seek help from the community.
