I have trouble following your installation guide regarding the IPOPT solver. I use Windows 10 with Matlab 2018b and your current version of ICLOCS.
On your website you state several ways to get IPOPT:

[...] can be obtained freely from Github toghether with the MATLAB interface.

While this repository does provide precompiled binaries and libraries, there is no matlab interface.

Windows users are recommened to install OPTI Toolbox which will have IPOPT included.

The given link leads me to a "404 Not found" error. A google search lead me to http://www.i2c2.aut.ac.nz/Resources/Software/OptiToolbox_Original.html. Sadly, the download links on this website cannot be found either.

While encountering this issue I also found that in the function file "solveSingleNLP_DirectCollocation.m" you say in the description that a "ipopt.mex" file is required. In the code a function "ipopt_auxdata" is used, but no "ipopt" function. Would it make sense to update the description?

I suggest using https://github.com/ebertolazzi/mexIPOPT for IPOPT. For me it works for both R2019b and R2022a
