Unless there is a specific reason why you would need the 2020 version, I would recommend downloading the current (2023) release from https://manual.gromacs.org/current/download.html.

It seems to be related to this bug GROMACS 2020.6 does not compile with gcc 11 (#4289) · Issues · GROMACS / GROMACS · GitLab. Apparently it’s an incompatibility with your compiler. As we’re not fixing issues in 2020 anymore, you will have add #include <limits> to the include block (early in the file) of src/gromacs/modularsimulator/modularsimulator.h. I hope that helps.
