Re: X-T4: no more than 4096 pictures?

It seems that I've stumbled into a severe bug of the X-T4. I took lots of pictures of an event, but lost quite some of them (ca. 200 of ca. 2200). When opening the SD card, I found out that the camera had stopped saving pictures after the DCIM/101_FUJI folder contained 4096 files (2048 .RAF raw files + 2048 JPEGs), and didn't create a 102_FUJI folder, but essentially wrote pictures into the void after 4096 had been stored. (4096 = 2^12 = 12bit, so this looks like some computer bug.)
I used two Lexar 128 GB V90 SD cards with dual card/redundant saving enabled. Both had been formatted in-camera before the shoot. Both cards ended up containing the same files, but didn't contain any more pictures than the 4096 in DCIM/101_FUJI. Both cards weren't full, but still had 32 GB free space. I also got no error messages when shooting the pictures after the ones that got saved.
The camera has the latest firmware (1.20).
Has anyone encountered the same issue? (Needless to say, it's rather disturbing...)
The same issue affects Macs reading SD cards from Fuji cameras with the latest firmware update, inc my X-T3. Older firmware only allows 999 files in a folder before creating a new one, whereas with the firmware update, that limit is 9999, and hence showing the bug previously hidden. The bug seems to be how the camera writes the directory entry, as the files are still physically there, but the Mac (and Linux) can't see more than the first 4096 files in any one folder (there can be other folders with up to 4096 files).
MacOS, and I presume Linux (I don't have a distro to test), has no problem reading and writing any number of files to a folder on the SD card from the Fuji, even the folders with hidden files. And it can import all images by connecting the camera via USB.
