Issue in installing power bi

Please check the minimum requirement of installing Power BI Desktop first: Minimum requirements 

• Windows 8.1 / Windows Server 2012 R2, or later
• .NET 4.6.2 or later
• Internet Explorer 11 or later
• Memory (RAM): At least 2 GB available, 4 GB or more recommended.
• Display: At least 1440x900 or 1600x900 (16:9) required. Lower resolutions such as 1024x768 or 1280x800 aren't supported, as certain controls (such as closing the startup screen) display beyond those resolutions.
• Windows display settings: If you set your display settings to change the size of text, apps, and other items to more than 100%, you may not be able to see certain dialogs that you must interact with to continue using Power BI Desktop. If you encounter this issue, check your display settings in Windows by going to Settings > System > Display, and use the slider to return display settings to 100%.
• CPU: 1 gigahertz (GHz) 64-bit (x64) processor or better recommended.
• WebView2, if not automatically installed with Power BI Desktop or uninstalled. Download and run the installer for WebView2.

When it meets the requirement and still has the same issue, you can try to uninstall the previous version wholely, restart your device and download the latest version of Power BI Desktop from website:
