Norton 360 running on Windows 10 21H2

During the past week I have had to remove and reinstall Windows 360 twice. I have two questions:

1) Can I reinstal Malwarebytes Premium now or are there incompatibility issues?

2) Even after the second re-instal of Norton 360 I have found the backup is failing owing toan internal error. Is a patch forthcoming?

It has been a trying week. Any assistance will be appreciated. Thank you.
