The interesting part from the log was left out here, the problem is: https://github.com/JuliaRegistries/General/blob/17357a5c1c15c67fa8ec591c82f3263af6befbef/Q/QueryOperators/Compat.toml#L20
QueryOperators is not compatible with IteratorInterfaceExtensions 1.0

[nalimilan]

Looks like it's caused by JuliaLang/Pkg.jl#110. So the only solution is to port QueryOperators to IteratorInterfaceExtensions 1.0. @davidanthoff Is that going to take a lot of work?

[nalimilan]

ActuallyQueryOperators already supports IteratorInterfaceExtensions 1.0: its Project.toml file doesn't have an upper bound, and tests pass. See JuliaRegistries/General#494.

Closing since this isn't a Tables.jl issue.
