Will Photoshop 2019 CC still run now it's no longer available to download?

I've been using a combination of the latest version of Photoshop and Photoshop 2019 for output sharpening via the free Google Nik Collection (which isn't compatible with more recent versions of Photoshop) on a PC for several years, but when I download Photoshop 2026, both Photoshop 2025, and 2019 versions of Photoshop were uninstalled from my system, and when 4 days later I tried to revert my system to an earlier point in time using system restore to get them back the only option I got was a revert back to before a Windows update from 2 days earlier that was after Photoshop 2019 had been removed.

I've since discovered that Photoshop 2019 can no longer be download from Adobe like I had after previous Photoshop version updates, so as far as I can see I've now got two possible options to get the Nik out sharpener back.  I can either pay DXO £119.99 for the full Nik Collection 8 which seems steep as I'll only be using a small part of that collection, or revert my system back to when I last did a complete system back-up which I was surprised to discover was over 3 years ago (so would require a lot of software reinstalling).

Before I try the later does anybody know if Photoshop 2019 CC will still run as part of a Photography Plan subscription?  I don't want to go thought the time consuming hassle of reverting my system then find it won't run because Adobe no longer consider that version to be part of my plan.
