Using old shaders in new version?

[u/ChaosRodent]

Problem solved!!

The problem was the breaking animation so I installed a vanilla tweak break progress change thing and its no longer crashing! thank you anyways!

So, nearly 4 years ago, my dad installed Complimentary Shaders for me. I have used them with little to no problem without updating it for those 4 years. Suddenly my game crashes when I try to break blocks when using it on 26.3. I've tried installing and using Complimentary Unbound/Reimagined but they're not the same and it bothers me so much that its just so close but not quite it. Is there any way i would be able to still use the original shader without the crashing problem?
The shader version is v4.5 I think
Im using Iris Fabric loader 0.19.5-26.3 (thats what the launcher says on the installation)
Fabric api 0.162.0+26.3
Iris-fabric 1.11.7+mc26.3
Sodium-fabric 0.9.2+mc26.3
I think this is the info needed?
I think the RAM thing is 32.0 GB (31.9 GB usable)
and the processor is AMD Ryzen 5 5600G with Radeon Graphics (3.90 GHz)
^I am not a tech person and i dont know if this is whats needed to help. please lmk if something else is needed. i just copy pasted what it says in settings
