Updated Postman can't connect to Postman server

I just updated to version 11.21.0 and restarted my computer. When I restarted, Postman showed a message that it couldn’t connect to the Postman server and, when I try to go into workspaces, it says “Couldn’t load the workspaces. Just a faulty wire. Try reloading.” However, restarting doesn’t change anything.

I’m facing a similar issue, but I have v11.22. After clicking on “Restart” to upgrade postman, I can see the Collections menu with a list or my requests, but the main section with the request tabs never opens. I can’t click any buttons on the app as well.

On the main.log file I could see this:

[65104][1733503481728][main][info]["INTERCEPTOR CONNECTIVITY: Attempting to start websocket server on port 15611"]

I found a workaround to fix my problem. Sending here some notes for whoever faces this issue… and also possibly helping the Postman team to debug it.

First, I downgraded the software to v11.19.0: https://dl.pstmn.io/download/version/11.19.0/win64

That actually didn’t help, so this step may not be needed.

I found on the logs ( renderer-requester.log ) these lines:

[54248][1733510389866][requester][warn]["ListingAPIAdapter~_getUnsubscribeAPIResponseWithSocket: Failed to unsubscribe entities",{"name":"Error","message":"CollectionListingAPIAdapter~getListUnsubscribeAPIEndpoint: not implemented for parent workspace","stack":"Error: CollectionListingAPIAdapter~getListUnsubscribeAPIEndpoint: not implemented for parent workspace\n    at n.getListUnsubscribeAPIEndpoint (https://desktop.postman.com/_ar-assets/common-651f0addde1f1ffe.min.js:1321:341466)\n    at n._getUnsubscribeAPIResponseWithSocket (https://desktop.postman.com/_ar-assets/common-651f0addde1f1ffe.min.js:1321:205947)"}]
...
[54248][1733510390541][requester][warn]["VariableGetter~getEnvironment - undefined was missing type property. All environement variables should have a type property"]
[54248][1733510390542][requester][error]["CollectionDefinitionInterface~fetchTypedCollectionConsentStore: Typed collections feature is not supported."]
[54248][1733510390543][requester][error]["CollectionDefinitionInterface~fetchTypedRequestDefinitionStore: Typed collections feature is not supported."]

Which made me think that it could be related to the tabs that were open (which had the state saved).

Then I cleared the window file (inside C:\Users\johndoe\AppData\Roaming\Postman\window), setting it as a blank file.

After opening Postman again, it went back to work. The tabs that I had opened were not there (and I’m not sure if I can recover unsaved requests), but things are working again.

For the record, I see this error when I try to open the same request I was using (a POST with form-data and a couple of env variables), but without a selected environment… and that makes my Postman window to break again (but clearing the window file puts me back on track)
