The exception code c0000005 is a memory access violation, but there are a variety of possible causes. If the faulting module name was something else it could narrow down the source of the problem, but unfortunately since it is the game executable, it isn't very helpful.
Please email supportdos@larian.com, with a description of the problem (or link to this topic) and the report.zip file (or a Dropbox or Google drive link, etc) generated by the
D:OS EE Analysis Tool (for Windows).
Extract the zip file somewhere and run AnalysisTool.exe. When that loads, browse to the install folder (if it is not automatically detected), optionally run the tests first, and then generate a report (it will be saved in the same location as the Analysis Tool).
The report will contain system and game information, as well as your saved games. To reduce the file size, you can delete all but one of the saves from the zip.
Also check the '..\Divinity Original Sin Enhanced Edition\Shipping' folder for any CrashDump files, and either add a couple to the report.zip file, or zip them separately.
