Hi @Zurina !

I think your issue is already covered(#21110), but I cannot confirm as not the whole stacktrace is posted. Could you add that part, the part after the lines below?

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x49a99e6]

[Zurina]

Hi @aristosvo, sure thing. I've updated the initial comment with the full stacktrace 👍

[aristosvo]

This is indeed a duplicate of #21110, as such I'll close it for now.
