BUG Rider 2020.1 won't reopen solution in Unity but keeps idling in Task Manager

I had to uninstall rider because an update went sideways. So, I reinstalled Rider using Toolbox. In Unity Rider will open on my first click of the script in my project but won't reopen when I close it and try to open the same script. It just idles out under the Unity Editor in Task Manager. If I end this task I am able to reopen rider when I click on the script in Unity.


I fixed this problem by deleting this version of Rider and using an older version. This is a massive issue for Unity developers and therefore the 2020 version is not usable at the moment.


Hi John!

Unfortunately, it looks like you have faced a known issue IDEA-236491. We are going to include this fix in our bugfix, that we expect in a couple of days. As a temporary workaround, please, try to stop Rider process in the task manager.


The bug is still existed.

Unity 2020.3.15f2

Rider 2021.2 M1

Macbook m1

Any idea???
