Running Snapchat on a rooted Samsung Note 9 with Magisk and LSPosed can sometimes lead to unexpected crashes, especially when using SnapEnhance for customization. This guide details steps to address Snapchat crashes, specifically when using SnapEnhance version 2.1.0 on a rooted Note 9 with Magisk v28 and LSPosed v1.10.1 (7119) debug.

**Error:** You may encounter a repeated issue where SnapEnhance fails to generate mappings, resulting in '3 warnings occurred while generating mappings' messages. These warnings often relate to properties like 'runFriendDurableJob', 'class', and 'onNavigationEventMethod'. Following this, Snapchat may immediately crash when launched.

**Steps to troubleshoot:**

1. **Examine Log Files:** Carefully review the generated log files (see example logs provided, if any) from SnapEnhance and Snapchat. Look for error messages or specific mentions of property serialization issues.

2. **Verify Compatibility:** Double-check that both Snapchat version 12.59.0.62 and SnapEnhance 2.1.0 are compatible with your Note 9's specs and the Magisk and LSPosed configurations you're using.

3. **Update SnapEnhance:** Ensure you have the latest version of SnapEnhance installed. Developers often release updates to fix compatibility issues and resolve known bugs.

4. **Test with Debugging Disabled:** Try disabling debugging within SnapEnhance. This can sometimes help if the debug mode is interfering with Snapchat's operation.

5. **Report to Developers:** If the issue persists, consider reporting the problem to the developers of SnapEnhance and Snapchat. Providing detailed information about your device, software versions, and log files can assist them in identifying the cause and finding a solution.
