On Windows the File Backed Collection's close failed when it tried to remove the temporary director it was created because the files were open.
This only caused issues on Windows because on Linux you can delete opened files while on windows you cannot.
The files were open because TemporayDirectory's close got called earlier than it should.
In my fix I got rid of TemporaryDirectory and handled temporary directory removal manually (which actually we did as well in the code). (Unfortunately with TemporayDirectory you can't control temp directory removal (you can only in Python 3.12)
