Magisk Crash on Module Installation: Troubleshooting on Android 7.0

Installing modules through Magisk can be problematic, especially when encountering crashes. This guide aims to help users troubleshooting a specific issue on Android 7.0 devices where Magisk crashes during module installation with the error 'Copying zip to temporary directory'.

**Understanding the Issue**

This crash typically occurs after patching the boot.img and flashing the patched image using Fastboot. The error message suggests an issue while copying the module zip file to a temporary directory, hindering the installation process.

**Troubleshooting Steps**

Given the device information provided (RCA Voyager III, Android 7.0, Magisk v28.0), here are some potential steps to resolve the problem:

1. **Verify Module Files:** Ensure the module zip file is not corrupted or tampered with. Download it again from a trusted source.
2. **Check Storage Space:** Make sure there is sufficient free space available on the device's storage. Module installations require temporary space.
3. **Permissions:** Ensure Magisk has the necessary permissions to read and write to the temporary directory.
4. **Logcat Analysis:** Examine the provided `logcat.txt` file carefully. Look for specific error messages or stack traces that offer clues about the cause of the crash. Search for messages related to file access permissions, file system errors, or Magisk functionalities.
5. **Reinstall Magisk:** Sometimes, a clean reinstall of Magisk can resolve issues. However, remember to properly back up your data before proceeding.
6. **Alternate Installation Method:** If possible, try installing the module through a different method, such as using Magisk Manager's direct installation feature.
7. **Contact Developer:** If the problem persists, reach out to the developer of the module for assistance. They may be aware of known issues or have specific solutions.

**Additional Tips**

* Use a reliable, up-to-date version of Magisk.
* Keep your device's software up to date.
* Double-check compatibility with your device model.
* When in doubt, seek assistance from the Magisk community forums.
