**Update — workaround found, likely root cause: special characters in display name**
I was able to fully resolve this on my side by changing my in-game display name.
Old name pattern: `[name] || [suffix]` (contained spaces and double pipe characters)
New name pattern: `[name]_[suffix]` (alphanumerics and underscore only)
After the rename, squadmates no longer crash when I become a deathbox. Confirmed across multiple Ranked matches.
This strongly suggests the bug is a string-parsing / serialization issue triggered when other clients render a deathbox owned by a player whose display name contains certain special characters (likely `|` and/or spaces, possibly other punctuation). It would also explain the self-crash cases I mentioned earlier: when my deathbox was rendered in the same frame as another teammate's deathbox (e.g. in the squad status UI on a full wipe), my own client also had to parse my name string and failed for the same reason.
Posting this in case it helps other players hitting the same issue — try renaming to alphanumerics + underscore only as a temporary workaround.
Leaving the original report up for engineering reference.
