Cannot read file ... - 3.5.2 - Win10

I ran into a situation, where a freshly saved score could not be opened afterwards, eventually. Now it seems to me that this occurs more often since V 3.5.2. I'm well aware that without a reproducable test case it is hard to fix it and unfortunately I can't provide one, either. As before, the container.xml is still valid, while all other information in a 60 kB file has a value of binary zero.
Is there anything I can do to minimize the risk of running in this situation again, or is this issue completely undetermined , although it is known for some time?
