Hoping to add to Ann's reply.....
I've had success with using windows "gamer" laptops in the $1000 range. Currently my computer is a Lenevo Legion and it does well with all the Adobe products (including when used with H.264 and H.265 footage.)
So far, I've not needed an internet connection to run Adobe software. There may be restricted use of some of the new AI features like the denoise tools in Lightroom or Photoshop. I've not verified that because I normally have a fast connection. Be careful with other software like Windows ClipChamp that appears to need server connections to fully function.
I don't work for and am clueless about Adobe strategy. That said, leading software companies have to be serious about support. As software ages, support becomes increasingly difficult. Limiting Premiere Elements to a 3 year life should not be scary. It should encourage you because I suspect it may improve support for those customers that sign up. Video has become so popular and common there are plenty of NLE choices. If paying for Adobe's software and support is objectionable to you, consider trying some of the free stuff.
