Thank you for showing the additional information, sadly it looks like you can not kill it , actually you could, maybe, but it is not simple, quick etc.
So, I see 2 choices, just reboot, I know you don't want to, but , if you consider how much time has been spent on this thread, and how much time would have been spent if you just rebooted, but anyway, now you know, ------
Or, the other choice : I have read this:
https://tanelpoder.com/2013/02/21/peeking-into-linux-kernel-land-using-proc-filesystem-for-quickndirty-troubleshooting/ You could read it, and try some of the things it shows, but it is complicated, and even then, it still might not be possible to kill it.
by kerryhall » This is a problem with the kernel, full stop. I only hope the kernel provides some sort of compilation flag such that I can say "Yes, I do want the ability to kill a process in the uninterruptible sleep state."
I don't believe there is such a flag, but that would be a 3rd option, send this in to the developers, as a bug report, for details:

by kerryhall » ----snip----and I'm tired of rebooting my system every time an SD card has a little trouble. I want my uptime measured in months, not hours, and I use SD cards dozens of times per day, phone, rpis, dashcams, DSLR, etc, etc.
Is this something that happens often ? Maybe consider trying a different file manager, check your hardware and SD cards, etc. This should not be occurring that often, if at all,.....are you sure you are umounting, ejecting correctly ? I have noticed over the years, busy people tend to pressure their selves, and try to rush things way to much, thus making mistakes , and actually causing their selves more problems and down time, where as a careful patient person, may seem slow, but in the long run they get more done, and more "up time", because very seldom do they break things, or make mistakes that cause system problems and down time. I am NOT saying that you are to blame, just saying, I would try to find the cause of the problem, that seems to be occuring when you use or change SD cards, phone, rpis, dashcams, DSLR, etc.Are you unplugging some and plugging in others, I also have had trouble with Thunar, crashes...and kind of stopped using it , most of the time, often the crashes have left me with a "locked up" system, but that would be another topic, simply using a different file manager solved that for me...take care and have a good day
