The non-aot stacktrace looks like
System.FormatException: Input string was not in a correct format.
at System.Number.StringToNumber (System.String str, System.Globalization.NumberStyles options, System.Number+NumberBuffer& number, System.Globalization.NumberFormatInfo info, System.Boolean parseDecimal) <0x1ce4bf0 + 0x00124> in <filename unknown>:0

at X.Main () [0x0000b] in <filename unknown>:0
The important part is
" at M.Foo (System.Collections.Generic.List`1[T] arg) [0x00001] in <filename unknown>:0 "
which has List`1[T] which is not enough to determine correct overload.
Note: When I was looking into it I noticed we expand the generic argument in complex cases only, e.g. IEnumerable<int[,,,]> which is probably different bug.
