As it happens, I just experienced the same thing with my X-T5 this past weekend.
I was shooting an event in the Pre-shot ES mode (continuous focus, electronic shutter, high speed continuous etc) and it worked fine until it didn't. There were a number of times when after taking a series of shots the camera "froze" as you describe - nothing short of removing the battery got it working again, including "turning it off" (which shows us that 'fly by wire' systems can make for some confusion.
SanDisk Extreme Pro 256GB cards - that I have used numerous times before without issue, and formatted in camera prior to the shoot.
Puzzling, to say the least - perhaps Fuji has a firmware update comout out to fix this?
@SimonF, the same image sequence used to make star trails can also be used to make time lapse videos.

Note 1: This is a .mp4 video file. Unfortunately, some browsers will not play these files, but there are plenty that will play them. Hopefully, those reading this will be able to view the file.
Note 2: This time lapse sequence shows Taurus, the Pleiades and Perseus rising in the sky. Along with a lot of other 'regional sky stuff' as well.
