Postman Win10, Not starting

I am having problems with the latest version of Postman on Windows 10. Specifically 10.12.x.x (latest version downloaded from Postman site on 3 April, 2023. This has a couple of different factors which I will explain below.

  1. If I start at Postman 9.31.0, I can install, startup, sign-into my Postman free account and run normally.
  2. If I then allow Postman to update to latest version, this installs, OK initially.
    2.a Usually first start-up after update, the UI never comes up, looking in task manager it has started 4 Postman.exe processes though. Usually if I kill those, then restart again, it starts up and shows me as logged in.
    2.b After a couple of days, using it off and on, when I try to start, when the UI comes up, it shows me as logged out. When I login it gives me the browser (chrome or edge) login, which I do successfully, then when switching control back to desktop app, it goes away, UI doesn’t come up, again 4 Postman.exe processes running in background.
    2.c Sometimes if I start the old or the new version directly from the version folder user %userprofile%\AppData\Local\Postman[version-folder] it will come up and be logged in OK, especially with older version.
    2.d Other times new version will not start or if it does won’t show me as logged in.

3 If I install the lasted version after uninstalling and cleaning the AppData Local & Roaming folders completely. Upon startup, the UI never comes up, 4 background processes are running. Nothing I do startup wise like the above makes a difference.

So in the end, my only current workaround is to remain on the old 9.x version.

Any thoughts or suggestions?

Hi @mjwsfg

Is this a personal or work computer?
Our work laptops have had security policy/proxy issues that have stopped some apps from working properly.
However, if this is a personal computer I suspect its a different issue.

Work computer. I suspect something specific to our environment, but none of the normal tools are throwing messages indicating anything is getting blocked. I can replicate it on a couple of machines.

Additional notes: I confirmed that Postman 10.8.0 and 10.12.0 both get the issue, along with current Postman Canary version 10.12.11

Still fighting this issue, which still occurs on latest version, 10.14.2. Below is the main.log (randomized). In this instance, I started with a clean install (folders out of %userprofile%\Local and %userprofile%\Roaming were deleted). Installs OK, starts up, no workspace, login directs you to browser, auth is OK there, redirects back to Postman, which restarts, but still not logged in.
