Scratch is crashing when I backpack a block

My browser / operating system: Windows 7, Chromium 146.0.0.0, No Flash versions detected
My browser / operating system: MacOS 13.4 (mom's computer), Chrome 144.0.0.0, No Flash versions detected
Seems to happen without extensions too. On an alt account, I tried backpacking one motion block, and Scratch just immediately crashed. It was also happening on my main account.
Edit: Weird i'm getting it on some accs but not others? Happening on orthocenter but I don't have that much in my backpack there

I can tell you, that is not happening on my end
tho maybe it's because there are spaces, weird spaces on my end

Yeah, I'm not sure what might be causing it bc I don't have a lot of stuff on that alt that I tried.
I also just tested it, and I was able to backpack costumes (an image as well as sth from the costume library), sounds, and a sprite with the block. It doesn't seem to always happen now.

Edit: weird I was just able to backpack a script with more than 1 block, but it crashed when I backpacked a block right after. So it prob doesn't have to do with backpack size

It doesn't seem to always trigger for me, and I haven't got the crash with more than 1 block yet, and I've been able to backpack everything else. The problem doesn't seem to be related to backpack size if I'm able to backpack a script with more than 1 block but then not be able to backpack 1 block (even if I delete the script) though
Also, Scratch (not my computer) crashes for me.

Interesting bug…

Cannot replicate easily. (I didn't try super hard lol.)

Are there any errors in the browser console?

I'll try to see (maybe try adding a single block until it crashes)
Edit:
TypeError: Cannot read properties of null (reading ‘getSvgRoot’)

Is it only when backpacking blocks, or does backpacking other things also trigger a crash?

As I said (I couldn't get it to happen with scripts with more than 1 block), other things didn't seem to trigger it

I wonder if it's related to specific SVGs then?

Does that fix it, or is it just a suggestion?

I've already logged out and logged back in multiple times while replicating this issue, so it doesn't seem to fix the problem

Hello from Japan :) I used DeepL translation.
My browser / operating system: MacOS Macintosh X 10.15.7, Safari 18.6, No Flash version detected
In my environment, adding the following block to the backpack causes a crash.
(list::list)
This issue reproduces every single time.

For me it crashes if I grab the block from the block palette, and it doesn't if I grab the block from a script

I've had it crash with both I believe, but I could be wrong
