Your settings likely weren’t deleted but are just stuck in a settings folder specific to the old photoshop version. So, you might be able to restore everything by copying the content from the old settings folder to the new one. This link has settings folder locations: helpx.adobe.com/photoshop/kb...

Going into the new year, I’m not going to pressure myself to make any finished art, but instead just focus on making a habit of sketching regularly and having fun with it again.

As someone who used to love IG for discovering new artists, I hate how the platform is increasingly destroying reach for actual artists like you in favor of that stuff + video. Sorry you and others are having to deal with that!
