I don’t see any errors in dmesg
EXT4-fs (sda4): mounted filesystem r/w with ordered data mode. Quota mode: none.

No problems here - I just mounted a SanDisk 64gb USB yesterday and wrote to it no problem (using ‘rsync’). Admittedly, I didn’t try to save a LibreOffice PDF.

Did you copy the PDF using the CLI “cp” command or a file manager app … or did you Save the PDF to USB while in LibreOffice??

(BTW - instead of checking dmseg, might use journalctl for clues).

For fun, I fired up Libreoffice and opened a file, then did an Export As = PDF and selected a sub-directory on a USB stick and it saved it within a second or two. USB is formatted as ext4.
