User reports four Windows BSODs in four days tied to Claude desktop, crash pinned to bindflt.sys

A user filed an issue claiming their Windows machine blue-screened (STOP 0x50) four times over four days, all while using Claude products: twice in the Claude for Excel add-in, twice in the desktop app chat, the last pair just 11 minutes apart.
- All four minidumps are identical: same bugcheck code, same faulting instruction offset, byte-for-byte identical call stack
- Every faulting thread belongs to claude.exe; the crash occurs inside Microsoft's bindflt.sys bind-mount driver via FLTMGR, likely tied to the desktop app's connected-folder feature
- The reporter argues this is a deterministic code-path bug, not pool corruption or bad RAM
The issue is currently labeled invalid and unconfirmed by Anthropic.
