Curseforge logs say the reason it crashes when advanced xray is enabled:
Mod ID: 'neoforge', Requested by: 'xray', Expected range: '[21.8,)', Actual version: '21.7.25-beta'
Mod ID: 'minecraft', Requested by: 'xray', Expected range: '[1.21.8,1.21.9)', Actual version: '1.21.7'

I understand this but I have minecraft 1.21.7 and I installed it with curseforge, the version I picked was neoforge 1.21.7 cuz that is what I am playing on. I also saw on someone elses issue that this may be the wrong place to post this but I did not see a comments section on the curseforge website for Advanced Xray(Neoforge Edition)
