i have no ideas

I haven't gotten the extension to install correctly with SIP enabled .
Have you succeeded?
Have you tried removing “com.apple.developer.system-extension.uninstall” from your application, since that doesn’t seem to be a real entitlement. And then have you tried removing app sandbox and get-task-allow from your dext’s entitlements?
