Same issue here. If you have any advice I would not be more grateful ! @zhanghao-njmu

When I install packages using 'devtools::install_github("zhanghao-njmu/SCP")', it occured the error below:
Error: object 'LayerData<-' is not exported by 'namespace:SeuratObject'
Execution halted
ERROR: lazy loading failed for package 'SCP'

• removing 'D:/Program Files/R/R-4.2.2/library/SCP'
  Warning message:

object ‘LayerData<-’ is not exported by 'namespace:SeuratObject'.
I try to found where use 'LarerData<-' in package, but I can't.
It's very streng. I can't found the reason why it happen.

这似乎是因为scp默认安装了seuratobj5，手动降级到4后再加载就可能会出现这个错误，但是我不知道如何解决

The "LayerData<-" is the special matter in SeuratObj5, I try to find what function using it in the SCP, but I can't. It‘s very odd.

经过测试，通过下面的命令可以解决这个问题，其实就是使用Seurat 4，以及SeuratObject 5就可以了，你们可以尝试一下。
After testing, the following command can solve this problem, which is actually using Seurat 4 and SeuratObject 5, You can try it out.
remove.packages(c("Seurat", "SeuratObject"))
install.packages('Seurat', repos = c('https://satijalab.r-universe.dev'))
install.packages('SeuratObject')

Thank you for your suggestion. However, it seems that Seuratobj 5 has undergone significant changes compared to version 4. Have you tested the compatibility between Seurat 4 and Seuratobj 5? I am concerned that conflicts between them might cause the existing analysis pipeline to fail.

After modifying the Seurat version based on my description, I tested it on a dataset and all analysis and drawing processes worked properly.
