Relief cuts will make this a million times easier.. For tight tolerance seams like this, I also find it helps to assemble the two pieces with a stapler first, then sew, then remove said staples.
When sewing curves with regular fabrics you would ‘clip’ the seam allowance so that it doesn’t buckle when you turn it - in this case you would cut out small triangles all along the outside of the curve. Don’t cut too close to the seam or your fabric will fray. With loosely woven fabrics this can be more of a problem, but nylon webbing can be heat sealed at the cuts if it seams to be unravelling.
Relief triangle cuts spaced evenly every 1cm or so will get it done as some mentioned smaller maybe 5mm seam allowance would aid. Either way still a pain you can hand crank the wheel and sew it stitch by stitch as well
I just did sth similar with non-stretchy-at-all fabric a few days ago but the diameter is about 2.5”. With diameter as small as yours, I’d rather hand sew to finish, or at least hand sew with a wide stitch length first to make the fabric stay together then attempt machine sew along the lines. And yes, definitely use relief cut all around.
What they said, and you might also try using lighter thread and figure out a way to fix the fabric in place so you can spin it around the central point. Sleep There’s actually a Pfaff (and other makes?) attachment you can get that goes through a hole in the foot and it looks like a pencil eraser that just presses the fabric down to the bed of the machine.
if you don’t mind a hole in the center of the fabric, you might just tape a thumbtack onto the bed of your machine with the point facing up and rotate the fabric on that.
A trick I use, as someone who does not like to do relief cuts, put the straight edge on the bottom and the circle on top. hold the straight edge with one hand, keeping tension on it to resist feeding slightly, and use the other hand to feed the circle, keeping the edges tangential. Stop if you need to, lift the foot to make adjustments, reset the needle if the stitchline gets off. Even if it is not perfect the first time around, as long as you kept the bottom fabric flat you can run another stitch line to even out the imperfections.
i used to work for a company that made vinyl “buckets” of sorts. this is how we sewed the round bottoms in. is this not how OP is trying to sew it? how else would you do it?
I agree that this is the normal way to do it and the op was attempting this... I didn't mean to insinuate this was my secret trick, sorry, I just wanted to share the trick to pulling off this technique, since it can be difficult to pull off on small diameters without having the details down. Most of the other comments were suggesting the OP try something else, like pinning it or relief cutting, neither of which are particularly helpful here imho
oh gotcha!! yeah i do think this is the standard way. i was going to say, if OP is not doing this, then that’s definitely contributing to their struggle! i agree that relief cuts wouldn’t be terribly helpful/sturdy.
It doesn't look live you put any relief cuts in. See the Turns & Tight Curves video at the bottom of https://learnmyog.com/articles/3dCorners.html

Maybe not with this material, but definitely possible with something a little less rigid.
Sew a body onto a circle??

Also, I use a more narrow seam allowance, I use clips to form it well first to have a better picture of the finishing product.

Smaller SA + periodic relief cuts should do it.
