My game crashes when I transfer items inside the backpack while holding shift, it doesn't when I manually move items.
I'm in 1.19.2 with the Create+ [FORGE] mod pack, loaded with Curseforge on an Aternos server.

To Reproduce
Steps to reproduce the behavior:

1. Open backpack
2. Transfer any item inside in any way
3. Transfer it back to any inventory by holding shift and clicking
4. Crash (only client-side)

Expected behavior
The item transferring to my inventory without crashing

Versions
1.19.2-3.19.4.977

Yes it is, thanks, I'll delete smooth swapping

I will need the crash log to really know what's going on but sounds like just another case of smooth swapping mod to me
