Postman closing when clicking on Send

Hello,

When I open Postman using the latest version download,

  • It signs me in via browser prompt
  • Opens the Postman Desktop Client, and I can see all of my Collections
  • As soon as I click on Send on any API, desktop client disappears.
  • Now, when I try to launch it again, the client UI never shows however its running under the Task Manager.

I tried, deleting the folders, in Local and Roaming, killing the postman service in Task Manager, and still the same experience.

Any idea why, and what can I do?

I tried another PC in my organization, and same experience.

Is this bug in Postman app or there is a fix for this?

After the latest release, I was able to open up but after clicking send the postman just crashed and I was unable to open it up again, needed to remove the profile to be able to open it up again. login again but clicking send it just crashed again and the same state
