Launcher and Game can't connect to Steam API in Windows 7 after 2.20 update
New, NormalPublic
Actions

Description

The 2.19 launcher was working fine.

After updating to v2.20.152984 through Steam the launcher shows "Update unavailable, Steam is not running".
Launcher version is 1.5.15.2984
Steam version is 1690583737

The launcher doesn't show any server, and neither does the in-game server list.
If I manually connect to a official server using its IP address and port, it never loads the mission. After showing "<player> connecting", a message is shown that voice communicattions are disabled for security reasons. Screen keeps black forever.

This effectively leaves Windows 7 unsupported for every feature involving Steam, while the changelog says it should be supported up to v2.20.x.

Steps To Reproduce

Just open Steam and launch the game. The launcher fetches the news and then shows "Update unavailable, Steam is not running".

Additional Information

The installed Steam client might be old. Steam stopped supporting Windows 7 in 2024. It still works though.

The Server.Browser.Service.log doesn't show anything for the session.

A fragment of the Steam.Native.log file showing the last successful server fetch in April (using v2.19 launcher) and the failed one today:
