I can't seem to use any encoders other than x264 or I get this issue and I'm unable to figure out why. My drivers are updated, windows is updated, OBS is updated and ran as administrator, I've restarted my computer and opened and closed obs several times. I have GPU preference for obs set to high performance in settings. I would like to run AMD HW H.265 (HEVC) as my video encoder, I'm not sure why I can't. I'll add the log file, I'm hoping someone can help?

This sequence of messages in the log means, that the required component of the GPU selected for encoding is missing - no HW encoder inside. Some threads on this forum tagged with "RX 6550" says the same - there is no HW encoder inside this GPU, for "M" (mobile) version of the card for sure.

Likely, you problem started after:

...I have GPU preference for obs set to high performance in settings

so, try to revert the changes. Thus, OBS be able to use more modern GPU (the power saving core, build-in in your CPU) for encoding.
