There is no actual steps to the process, or errors. I installed Bolt and immediately cannot expand any of the Foldouts in the class inspector. Tried a restart with no change. I played with panel positions and hiding other windows, but also no change. I am not the only one experiencing the issues from what I'm getting from others on Discord.
EDIT: I can confirm this is a problem with Unity 2019.3+ and Bolt, I downgraded to 2019.2 and it works fine.
