I think this is a duplicate issue with bug 1837736. I submit a patch on bug 1837736. Let see if the patch helps on this bug or not.

appears fixed since build 20230719160709 in nightly. bug 1837736 has been uplifted to beta for 116.0b8. If there are no crashes there, I'll close this ticket as fixed
