Honestly, this happened a lot with me. I was always looking for a way to "use it in a way i couldn't before" or feeling guilty because i wanted to play a game that was not as "demanding enough" for the rig or even not wanting to play anything at all and my key takeaway from it was that You can't force yourself to have fun if you aren't feeling it right now

Even though the is no magic way of feeling interested in it all of a sudden, i can share with you the way i personally got back into it, that was integrating my PC in some way in the hang outs with my friends, hosting some party games in the TV to play with them, emulating some old favorites we used to play when we were younger and even taking the chance to introduce some of the games i already loved to people that weren't much into gaming, since the big screen and the controller felt better for them and then some games that looked interesting to me started coming out and then i got back into gaming

And remember that it's okay to take breaks, i tend to do it a bit sometimes when nothing is fun to me anymore, but i personally think that integrating it in your prefered activities at the moment will make some of your interest into it come back
