Thanks for trying to reproduce it. I am using using 5.5.1. I will try 5.4 as well and let you know if this is a regression

Hello everyone,
I tested 5.4.4 as well and it doesn’t crash. So this is probably a regression related to 5.5.1.
I have reported an issue for that

Glad you were able to narrow it down in that case.

Hey,

thanks for reporting the issue! We’re having the same problem after updating to 5.5.1. I worked with 5.4 and is still working when im downgrading back to 5.4.

Unfortunately I can’t find your report, could you please share it so I can upvote it?
