Hi @anandhpowerbi,
What version of power bi desktop are you used? (32/64 bit) If you are work with 32 bit, I'd like to suggest you switch to 64 bit to allow using more resources for data model table records and Dax expremison calculations.
Memory Limits for Windows and Windows Server Releases
How many available/idle system memory available on your device? Any complex DAX formulas you used in your report? (nested multiple iterations or looping across multiple tables)
If this is a case, I'd like to suggest you increase your system memory resource or optimization your expressions.
