Please email email@example.com, with the report.zip file (or a Dropbox or Google drive link, etc) generated by the D:OS 2 Analysis Tool
Extract the zip file somewhere handy (like the Desktop) and in the AnalysisTool_DOS2 folder, run corresponding executable. It should detect the game install path, but if not you can browse to the 'Divinity Original Sin 2' folder. 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 greatly reduce the file size, you can delete all but one of the saves from the zip (double click the zip file to open it in Windows Explorer, then browse down to the ..\Savegames\Story folder), just leaving one before heading to Reaper's Coast.
Also check the '..\Divinity Original Sin 2\bin' folder for any CrashDump files, and either add a couple to the report.zip file, or zip them separately.
