For what it is worth I highly suggest you look at taking in person lessons until you at least get to bar chords.
It will save you a lot of time and also prevent you from becoming frustrated. The way you use your hands will feel very wrong when you start and it is easy to fall into bad habits which will take you a long time to un-learn.
The guitar industry would fail if every person who was frustrated just pulled the guitar they have sitting under the bed and sold it. Sign up for a few months with someone who can watch and give you suggestions and it will be a lot easier to get past that initial steep learning curve.
Really learning how to relax while you build up the muscles is the critical part and it is pretty hard to notice your death grip without someone there to give you tips.
Once you get past that first bit, if you are the self motivated type, it is much easier but still slower to do so on your own.
But if “free” is the only option youtube has some good channels like this one.
