Backport fix for #126720 to the 20.x branch

[HighCommander4]

I would like to backport #126868 (which fixes #126720) to the 20.x branch.

This is a crash regression that's new in 20.x and can affect valid code.

(Maybe the backport process has changed recently? The last time I did a backport, a bot would create the backport PR after seeing the "/cherry-pick" comment.)

Ok, I see the bot did run, it just took a bit longer than usual.

(Not sure what the "failed to cherry-pick" comment is about, the backport PR looks correctly applied.)
