System Information
Operating system: Windows-10-10.0.22631-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2060/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 551.61

Blender Version
Broken: version: 4.1.0 Beta, branch: blender-v4.1-release, commit date: 2024-03-03 21:50, hash: 8f68dfe0c24e
Worked: (newest version of Blender that worked as expected)

As shown in the video bevel edge mark sharp are completely ignored, manual edge marks as well behave completely randomly depending on edge angle

mark sharp is how it is internally controlled when using auto smooth by angle from the right click menu, yet the geonode completely ignores any kind of marking

broken shading when using shade smooth and mark sharp(images)

Thanks for the report. Could you attach the file from the video so we can investigate this further? Or at least a file with that object included.

file has been added, it has nothing to do with the file tho, it's been like this since the 4.1 shade smooth change
this whole system should have never been regressed to this point

blender/blender#116922 also mentions in part the same issue as well as the whole concept of this new system being actively worse,
including blender/blender#118118 which brings up issues with backwards compatibility making it a one way trip that can corrupt files from my experience,
with additional mentions of mark sharp being non-distinguishable from a sharp edge blender/blender#114722

Sorry if I'm not getting something obvious, but could you describe in more detail what is wrong with the model? Or alternatively, could you share something set up in 4.0 that has this problem when moved to 4.1? Maybe I'm missing something but when I compare the file loaded in 4.0 and 4.1, I'm not noticing any meaningful differences.

the main issue here is the mark sharp is not behaving like it did before, and not working if the mark is generated with things like modifiers and such, barely works by chance when marked manually as shown in the first video

it acts as a modifier making the order of the stack confusing to find where in the stack will shade correctly ignoring anything below, simply putting it at the end of the stack doesn't work with every model, slows the entire modeling process needlessly to check for mark sharp and why a model looks wrong, takes longer to calculate by multiple seconds, needs to be at the end of the modifier stack for the shading to work but can create issues with other modifiers which need to be at the end of the stack to work, it's not just mark sharp making the main part of the issues it's when the sharp geometry is considered

needs to be at the end of the modifier stack for the shading to work but can create issues with other modifiers which need to be at the end of the stack to work
additional proof that, the geonode requiring to be at the end creates massive issues: 1 blender artist thread 2 blender/blender#116395
