The devs unfortunately cannot reproduce this bug.
Is there anything off-standard with your server setups?
Like a non-default codepage setting, or a non-default storage type for the /temp folder(s)?
I was going to reply that no, there’s nothing particularly interesting about the installation on which I tested.
However, I just re-tested on the latest beta, 1.43.2.10687, and can no longer reproduce the issue.
Updated to 10687 here (latest beta), the crash is gone, and it still contains the arrow lake transcoding fix.
