I am trying to upscale a 1080p 60p video to 4K.
I have set the correct resolution at the project settings

I try to render at 4K res with 150Mbs

It does not even execute

I have tried lower bitrate, even the DEFAULT UHD 2160p profile. I get the same result.
I can render only in Apple ProRes with these settings but the rendered video is skipping frames.
