Often, a blank Power Query Editor is caused by a temporary memory glitch or interference from overly strict antivirus software that blocks the editor's executable file.
Close Power BI Desktop completely. Open the Task Manager (Ctrl + Shift + Esc) to ensure no background Power BI processes are running, then relaunch the application.
Go to File > Options and settings > Options > Updates. Ensure you are running the latest version of Power BI Desktop.
Open your Windows Security or third-party antivirus software. Check the protection history or blocked apps list to ensure the Power Query Editor executable is marked as trusted.
Update Graphics Drivers and Reinstall
