Invalid sink argument after upgrading to julia 1.6

I updated to Julia 1.6 by downloading the generic linux and moving them in the folder I keep julia. I launched atom, reinstalled all the packages (I need to do it every time I update, so I try to upgrade as little as possible), but I got this error:

# from script

ERROR: ArgumentError: provide a valid sink argument, like `using DataFrames; CSV.read(source, DataFrame)`
Stacktrace:
 [1] read(source::String, sink::Nothing; copycols::Bool, kwargs::Base.Iterators.Pairs{Symbol, Char, Tuple{Symbol, Symbol}, NamedTuple{(:delim, :decimal), Tuple{Char, Char}}})

Essentially, I can’t open a tab-delimited file even if the packages are loaded.
How can I solve this issue?
Thank you

the error msg said exactly what you should do?

btw, you should do DataFrame(CSV.File()) now

Check out the docs for CSV.read. You need to tell the function what you want your output to be. CSV.read(path, DataFrame).
