Inspect crashed with illegal hardware instruction

[saicharan-kandukuri]

How can we reproduce the crash?

I got this error when i was spam refreshing debug.bun.sh for my bun project and after that --inspect does not work on any of my bun projects it either shows below error in site or crashes in terminal with panic: Illegal instruction at address 0x59443CD.
