I'm working in a company on several projects with InDesign CC 2015.4 (11.4.0.90 x64) and I'm fighting against very frequent randomly occurring crashes with no error message (just Adobe InDesign CC has stopped working). These occur 2-3 times within an hour, so it's very frustrating and I keep losing small amounts of work everytime which I have to redo. The crashes may happen during most tasks, as simple as selecting an object, but most frequently they happen when I may change the color of an object or apply or edit an effect. Another person in the company is having similar issues and it's really driving us mad. It'd be great if someone could help troubleshoot this, or even better if Adobe itself fixes these issues soon. Random crashes with InDesign and Illustrator have been common since forever for us, but lately it's more and more common.
Some extra info: In the Windows Event Viewer, the crashes usually have exception code 0xc0000005 (Public.dll) and 0xc000041d (Database.dll). We also tend to work on files on the local network more than locally on our computers.
