I don't know of any workarounds for this.
You can email supportdos@larian.com, with a description (or link to this topic) and a save just before opening/entering the Teller of Secrets portal for the first time.
In Windows you can use the
D:OS EE Analysis Tool to generate a report.zip file, which will contain system and game information, as well as your saved games. To reduce the file size, you can delete all but one the saves from the zip.
For the Analysis Tool, 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).
After deleting excess saves, you can either email the report, or upload it to Dropbox or Google drive link, etc, and include a link.
