Hi @SANDIP_PUND ,
Could you please try to update the SDK? The latest Swift release is 10.54.1.
These errors are too generic to provide a diagnosis: can you collect a full stack trace, that would at least give an idea whether this is indeed related to Realm, and which part of the code is failing?
If you’ve a Support contract, it would also be better if you engage with us there, to be followed properly.
