My Postman version is 11.47.1
Windows 11, version 23H2
When I click on the app, nothing happens, please help 
Not sure if it helps, you can check Windows Event Viewer–>Windows Logs–>Application for any additional information that might have been updated by Windows that led to the application from being loaded successfully.
This happened to me once too, and I followed the steps below to fix it. Hopefully, it helps you as well. Let me know if it works for you!
Clear Local Postman Data (Most Common Fix):
- First, make sure to back up any important local collections (if you’re not signed into a Postman account). You can do this by exporting them, just in case.
- Close any running Postman processes:
- Open Task Manager (Ctrl + Shift + Esc)
- Look for any “Postman” tasks and end them.
- Rename Postman folders to reset local data:
- Open File Explorer and go to these two folders:
C:\Users\<YourUsername>\AppData\LocalC:\Users\<YourUsername>\AppData\Roaming
- Replace
<YourUsername>with your actual Windows username. - Find the “Postman” folder in each location and rename it to Postman.old.
Note: If you don’t see the AppData folder, click on the “View” tab in File Explorer and enable “Show hidden items”.
- Try opening Postman again
Hi @aerospace-saganist-9 ,
Close the existing app and first login into web application to ensure all works is saved on the web application and then try re-installing and running the app again locally.
