Couldn't finish form because of self-intersection, which can not be deleted

Avoid triangles at all cost! So I removed that traingle and then used  the Make Uniform tool with Convert T-Points enabled

Avoid N-Gons and use complete edge loops.

As you can see in the screenshot, that creates much cleaner surfaces.

Nice work so far. Keep going!

Thank you so much for the solution, I think I should learn more about T-points and N-gons to avoid them
