OBS intermittently disconnects 2 minutes after switching scene

[Pistol Skin]

Over the past few weeks OBS has started intermittently disconnecting from Facebook 2 mins after switching scenes. An overview of what happens is as follows:

1. Start stream
2. Switch scene (note, this does not happen every time and occurs with different scenes)
3. 2 mins later OBS disconnects from Facebook
4. OBS tries auto reconnecting (up to 20 time) but is unable to reconnect
5. Facebook is still waiting for OBS to reconnect
6. I manually stop OBS from streaming by clicking "Stop Streaming"
7. I try to manually restart streaming by clicking "Start Streaming" but nothing happens
8. I try to click the button a few more times but still nothing happens
9. I restart OBS Studio
10. Click "Start Streaming" and it reconnects to Facebook

I have tried the following:

• Checked internet connection - I have no internet connection issues (and reliable connection)
• I have optimised MPU by following online instructions
• I have removed all large media files from the stream
• Decreasing audio bitrate from 128 to 96
• Decreased stream bitrate
• Increased stream bitrate
• I am connected directly to the router by cable
• Windows and all drivers are up-to-date
• OBS is up-to-date.

I use groups and scenes within scenes. I can seen that there is a current bug relating to these but not sure if this is what is causing my problem yet :

[BUG] OBS duplicates scenes and corrupts scene collections when using groups

I currently have 3 log files for this (last 3 streams attached). The information where this happens (and a summary from the logs) is as follows:

If anyone has any suggestions please let me know as this is killing my streams. Thanks.
