At a guess, rebuilding gjs with a current toolchain (or perhaps 
rebuilding gjs against the new mozjs) would probably resolve this. 
If you have arm64 hardware available, please try that?

(A binNMU of gjs might well already be in the queue, but the buildds are 
working through a very large queue of binNMUs so it could take a while.)
