What is this?! Appeared on 25 May 2021… no one else seems to be talking about it.

When you have a telescope in space pointing towards the sun, the imaging sensor is exposed to outer space. The solar particles that are send out by our Sun, can hit the image sensor causing these bright flashes and strikes across the screen. It's nothing out of the ordinary and is very common, during a space radiation storm it gets a lot worse than that (see image).

Is there a non-zero chance that it's solar ejecta aka dense plasma?

It was just visible in one frame excluding a solar phenomenon. I’ve revised the data of that moment in helioviewer to see it all.

Thank you!

that looks a lot like the noise pattern that was faintly blended over my field of view right after one of the 2012 solar flares became inactive in every morning day

It could be a comet's ice rubbing with solar wind. Needs link to video.

You can check it in helioviewer with the times mentioned on the images. No comets as it was just visible in a single frame, so it’s an energised  particle that hit the imaging sensor.
