Unprotecting the sheet and repeating the same call succeeds — protection alone is the trigger, not the range, not the workbook, not whether Excel is visible.\n\nv1.10.6 made this easy to reach by adding worksheet protection to the server.

Reproduced on v1.8.61 against two different .xlsx files in the same session. After the crash, the session is gone (subsequent calls return `Session '<sessionId>' not found`), and Excel.exe is left as an orphaned process holding an exclusive lock on the file — `file action=open` against the same file then fails with `Cannot open '...'.
