Issue with dimension line marking while Osnap is on

Hello, I am working on a 2D drawing as usual. Suddenly when I am trying to mark my dimensions of the figure, it’s not coming down the figure but I am able to mark it above it.
It’s kind of weird, when I turned off the Osnap and tried, it was working. But after I turned it ON, again it’s the same issue.
I am unable to understand what could have gone wrong abruptly.
Please help me with this. It’s irritating.
Thank you.
