It could be because of multiple reasons, check against all below points and hopefully will work.

• Check values.xml for bad characters or invalid resource names

• Ensure AndroidManifest.xml and capacitor.config.json have a valid package ID (no :)

• Remove plugins one by one and rebuild (especially OCR, preview, or file-related ones)

• Fully clean and rebuild the project

• Use --verbose to capture the plugin or file causing the issue
