Hulk: Hello there!
Have you tried installing Sandboxed Google Play yet?
If you already have it installed, please check if you have configured it properly.
More info on this topic can be found here:

6gsxdr3U To add onto this, if you find that running it with a properly installed suite of sandboxed play services apps (GSF, Play Services, Play Store) still doesn't work the following steps should be followed:
- Open the 'App Info' section for Tandem and make use of the Exploit Protection Compatibility Mode
- Run Tandem
- ONLY If it fails again, go to SETTINGS>SECURITY and disable Secure Exec Spawning
- Run Tandem
If it requires both of the above to work, ideally you don't want to leave the latter setting for Exec Spawning disabled, I would advise just toggling it off as required.
