Will the current version of Photoshop interfere with the operation of CS6?

I have been highly resistant to a subscription service but have finally decided to subscribe to the Photoshop.  However, I still have CS6 running on my computer and have some concern that the new version may in some way interfere with my ability to run CS6.  This is only important if I should decide to cancel my subscription.  I would likely have difficulty reinstalling CS6 under Windows 11 as my copy is one of a series of upgrades dating back to Photoshop 6.0, and I doubt Windows 11 will install the later version.  I doubt the current version of Photoshop would interfere with the operation of CS6 but I need to be sure.  Can anyone help?  Thanks!
