New OBS expects much newer CPU.
Code:
11:16:07.968: [qsv encoder: 'msdk_impl'] Specified object/item/sync point not found. (MFX_ERR_NOT_FOUND)
11:16:07.968: [qsv encoder: 'simple_video_recording'] qsv failed to load
Log shows that for
Settings > Output in OBS was selected (by you or by default) the QSV encoder from Intel. This encoder is part of the CPU.
Thus:
- if you need new OBS (v30+) you may try to select Software x264 encoder (it will run slower than QSV);
- or you can downgrade your OBS (to version v29.1.3 or so, where old CPUs and old QSV encoder was last supported).
The simplest way to downgrade OBS is to uninstall current version of the program, then download and install older version of OBS. Other way is to download previous (or any) version of OBS and make it portable in different folder on your PC (advanced users do this, like in:

Details about QSV:
I've been using QSV recording with OBS for many prior versions on Windows 10, but when I tried installing OBS 30.0 today my recordings will not start. I noticed in the recording settings screen there are now 2 different QSV options, one of them says "deprecated" which was what mine was initially...
