Ok, I'm not as familiar with AMF encoder settings, but this is the log error:
21:55:35.230: [AMF] [H264]<Id: 5> <Plugin::AMD::EncoderH264::SetProfileLevel> Failed to set to 31, error AMF_FAIL (code 1)
There seems to have been in the past a particular issue when using the AMF encoder with Vega cards, where the encoder tries to set the Profile level to a value that isn't supported by the hardware, with this error being the result.

You're on the latest OBS and Windows is up to date. I know that for some users, they needed to update their drivers, while for some users in some situations, they needed to roll the drivers back because the problem was introduced by the update. I don't know what the situation is currently.
In some cases this is caused by explicitly setting the Profile value to the wrong value, especially when set to Auto, and can be solved by setting it explicitly setting it to 4.1, but in some cases this did not work.
Wish I could be more definite, I just don't have a Vega card to test against.
