Failed to resume chat on old codex desktop chats, MXC launcher says SYSTEMROOT is missing

[Scottish Bible Basketb]

codex desktop on windows, old local chats wont open after the update

Failed to resume chat

error resuming thread: failed to load AGENTS.md instructions for environment `local`: fs sandbox helper failed with status exit code 1: MXC launcher: The supplied `process.env` cannot launch a Windows process container because it is missing the required variable(s): SYSTEMROOT.

only rollback to the 26.1016.8120 package helps. fix isnt shipped yet
