ARKit XR is not enabled error though it is enabled

Here, an error is rising while I am building a project in MAC for iPad. I am currently using MARS for the project and there is this issue.

Please enable the ‘ARKit’ plugin in ‘XR Plug-in Management’.
Open Project Setting > XR Plug-in Management > iOS tab and enable ARKit.

Although ARKit is enabled, the issue still says I have enabled it!

I have disabled and again enabled it, I have tried to build it on different projects and tried it on two different editors, but it didn’t work at all.

Versions:
Unity Hub: 3.4.2
Unity Editor: 2020.3.47f1, 2021.3.23f1
AR Foundation and ARKit XR Plug-in: 4.2.7
Unity MARS: 1.5.0
XR Plugin Management: 4.3.3

I’m having exactly the same problem here!
