Random hard crashing potentially relating to IKControls

greetings, i maintain a little virtual reality system known as HAKUREALITY, and have observed many hard crashes occurring at random with other players whenever a VR user is present in the same server.

when the crash occurs, the client immediately closes without log or crash message, which has confused many players.
this occurs regardless of operating system or device, and i highly believe this to originate from IKControls, as the crash does not occur when replication is disabled.

i have been unable to create a minimal reproduction as i’ve been unable to figure out how it’s occurring in the first place, any guess attempts have been unsuccessful.
however, if it helps, it happens often & has affected players in this experience when VR users have been present: ☒️ QS Energy Research Facility - Roblox

i have attached a private diagnostic report with this bug report, it was encountered with my own system, running macOS Sequoia 15.1 Beta 7.

a swift response would be appreciated due to the severe impact, thank you!
