OBS crashes while trying to start stream while another instance is running

[Twospace]

I recently got a new computer, and when I was trying to start streaming on another instance, it immediately crashed.

This is quite strange, as multi-streaming had worked fine before.

Crash in the core component of the OBS because of the recent changes in the code (Browser source updated and some updates to the profiles management). Because of deep dependency on 3rd party Browser code - no changes planned.

All related threads in one post (workaround is to use second instance of OBS in portable mode from different folder):

When opening two or more instances of OBS, the built-in browser source in OBS turns black and becomes completely unresponsive

打开两个或多个 OBS 实例时，内置浏览器源会变黑并完全无响应，而第一个 OBS 实例却运行正常。 我之前使用的版本（30.1.2）没有出现过这个问题。
