Hi @0jeetparmar0 , I am a LD19 user also encountering this issue.
You can refer to issues #4 and #11 of this repo. There also seems to be an opened pull request that fixes this issue, but have not been merged by the (rather inactive) owners.
Discussions about the root cause of this issue can also be found on slam_toolbox's repo (an issue raised back in 2020) and also similar repos utilising LDROBOT LiDARs
