I tried to precompile CSV into julia v1.84 but failed showing error message about call.  
I thought maybe the version update is the problem so I downloaded v1.94 and again have the problem.  
From import Pkg; Pkg.precompile(), I got the following report.  
Can anyone help me with resolving the problem?
