ArcGIS Pro 2.5 and R4.2.2 issue

[Linkaixiong1]

Hello, I'm not certain whether I have installed the R bridge or not. Currently, when I run ArcGIS Pro 2.5, the interface looks like the following screenshot. I am unable to run the software mentioned in this link: https://github.com/emrehanks/R-ArcGIS-LSM_ToolPack-64bit?tab=readme-ov-file. The software indicates that I haven't installed the R bridge properly. Can you please advise me on how to resolve this?
