I'm sorry you experienced this bug! 🙇

Looks like this problem was already reported though (#18859) so I'm going to mark this issue as a duplicate and close it. If you have additional context that might help us repro this problem, please leave a comment on the other issue!

Thank you~

@FatehAK This error remains the highest reported DevTools bug but we still don't have a repro case so that I can fix it. Do you remember how to repro the error you saw above? Can you share the steps with me if so? It would be very helpful! Thank you 🙇🏼
