We have the same problem, because we try to update python from the outdated version 3.7.1 to the most recent python version 3.12.0
Will there be a fix, or is RED no longer being maintained?

[lca-ebr]

What is the latest "known good" working combination of RED/robotframework/python versions?

Hello,

Will there be a fix, or is RED no longer being maintained?

No, RED is not maintained as stated in README.md file: https://github.com/nokia/red#important

What is the latest "known good" working combination of RED/robotframework/python versions?

RED was not tested with anything (eclipse, python, robot) that was released after last release of RED (mid of 2020). Especially RF have changed quite a lot since then and even RF 4.X is not supported.
