[HELP] how to using x265 in Hybrid correctly?

1. Using 1pass average bitrate is the worst encoding mode you can choose when aiming for a decent result. Better use 1pass constant rate factor.
2. If you don't know what settings do: do not mess with them until you understand them. The default values are usually there since they tend to give good results independent of the source content.
So first read up on the basics of MPEG compression, then read up on the specific changes AVC, HEVC brought and then read up an the specific encoder. An last but not least, do some encodes with a short test sample to get a better grasp what the impact on quality the features have.

Like the homepage states Hybrid is intended for advanced users., so it offers lots of options that you can change.
-> If you start with encoding tools like Handbrake might be easier to grasp.

Personally I don't really use thumbnails that much and usually add a cover art to clips where I need them.

but 1pass constant rate factor can't set bitrate, it sets like handbrake using number, the output file with loss more or less.
