Cannot use any of the ODEInterface.jl algorithms
I'm using Windows 64-bit and I can't get any of the methods in this package to work. I usually work in notebooks but below is a transcript from my terminal so the issues are clear:

If I try it in the notebook the error message is "Cannot find method(s) for radau! I've tried to loadODESolvers(), but it didn't work. Please check ODEInterface.help_solversupport() and call loadODESolvers and check also this output. For further information see also ODEInterface.help_install."

It seems like you don't have a working Fortran compiler? This is why we don't include ODEInterface by default: it requires specific compilers so you need to do a bit of extra work to get it installed.
