Any power shortage for example? It's a common root cause of such problem.
Check the temporary folder of the system (see in OOo Tools>Options>OOo>Paths). If there are folders like sgmlf.tmp with a file having the same name inside, make a copy of that file, rename it in .odt and cross your fingers. Else, I hope you had a backup (or a copy in a mailbox)...
NB: it seems that there are less reports about this with AOO 3.4.1.
LibreOffice 7.0.3 on Xubuntu 20.10 and LibreOffice 6.4.6 (portable) on Windows 10.
