1. Start LibreOffice (its Start Center). 2. In a file manager, open system TEMP directory (e.g., on Windows it would typically be C:\Users\<Username>\AppData\Local\Temp), and see the subdirectory created by the running LibreOffice process, named similar to lu147122n54x.tmp. (There might be many such subdirectories there - lingering from previous sessions that weren't terminated properly.) 3. Delete *all* the subdirectories named "lu*.tmp" from the TEMP directory, found at step 2. 4. In the opened LibreOffice, try to open any ODF file. => Write Error. The file could not be written. Was working OK in version 7.3.0.3. Gives the error in version 7.4.0.3.

FTR: the problem appears IRL in scenario of an (automated) temporary directory cleanup, which relies on proper file locking, which prevents currently used files from removing. It kind of makes sense on Windows.
Note commit c11d92791101e9bebffa6c0f5e53dc531f86e9c4 "#97276#: automatically recreate TempDir", 2002-03-18, which initially introduced ensuredir, and which seems to target the same problem.
