Power BI Desktop application is automatically closing

Hi Raghu2117 - It is likely due to a combination of large file size, resource constraints, and possible corruption or compatibility issues with the PBIX file.

Try opening Power BI Desktop in Safe Mode to prevent auto-recovery issues. Open a new file and disable Auto Recovery in Options > Global Options

Ensure your system has sufficient memory (16 GB or more) and storage space. Monitor usage via Task Manager when opening the PBIX file. As the file is large file sizes (e.g., 400 MB) can strain memory. Check for optimizations:
Remove unused columns and tables.
Use summarized or aggregated data.
Optimize DAX calculations and reduce the use of calculated columns.
Enable Large File Support:

If the data model uses large datasets, enable Large Dataset Storage Format under File > Options > Current File > Data Load.
Increase Memory Limit:

Adjust Power BI’s memory settings in Options > Global Options > Data Load > Power BI Desktop > Memory.

check on the above steps and i hope it helps.
