For PC, you can email supportdos@larian.com, with a description of the problem and the report.zip file generated by the
D:OS EE Analysis Tool.
Extract the zip file somewhere and run the 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 most of the saves from the zip; in this case you could just keep one before the escort quest, since this seems to be reproducible, or if you've done that already, your latest save and latest working save.
If the crash is reproducible, the CrashDump files wouldn't be necessary.
Console saves can be sent, as well, but they would need to be transferred to a USB flash drive first, then to a computer, and a third party tool is required for drives formatted for Xbox One (
see here).
