I’m seriously htiniking abotu goign with Affinity Photo which is similar- but woudl really love to keep photoshop as i have a ton of actions i built, and it works with plugins i bought- but if i have to i will switch as affinity is low price, $70, and it is forever- one time purchase- I think they will also offer subscription, but they claim they are keepign their perpetual liscence too- so that is a hufe plus- it does not do quite what photoshop does though- but close i guess-
You could always go the GIMP route, but I won’t personally recommend it since I hate GIMP myself.
Was never able to adapt.
