Additional context

[davidjgraph]

It tries to update from Github, is that the call you're seeing?

[TomyLobo]

I blocked network traffic. I'm not seeing anything. You should make the update not freeze up the application. It says "Checking for update" in the log I posted above, though

[m-mohamedin]

@TomyLobo I've tried it and it works. In snap, automatic updates are disabled. The log in my case says: "SNAP env is defined, updater is disabled" Which OS are you using, mine is Ubuntu 22

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions. See the FAQ for more information.

[TomyLobo]

I missed the response. will try this again with a recent version once I get to my work machine and have some time.

[TomyLobo]

I no longer got the ERR_PROXY_CONNECTION_FAILED errors in console with networking disconnected. I guess this got fixed in the meantime.
