I played with some friends in ranked, but I earn 2x less points than them…
I won 10 times in a row but I earn only 200-250 points per win while they get 500 points.
I also have the same win rate, and sometimes more than them (60%).
I am also having the same issue but I am only getting like 20-22 points awarded to me for a win and if I lose I lose 65-70 points. It has been like this for me the whole season. I am stuck in b5. I just had a friend get to s4 tonight and i have won more games and I have a higher win rate than they do. When i told my friends about how many points I was getting they all told me that they were getting 175-225 points. I tried to open a ticket about the issue but I was directed here instead. I see you wrote this post 10 days ago, has anything changed for you?

It is not a bug, that is how points work in Bronze 5 and has worked for years.
It has a different point system than other leagues. In other words it’s a whole separate league from the rest of Bronze (or other ranks).
The only way to start gaining ~200 points again is to grind into Bronze 4 and above.
