This question came to me when I answered in this thread https://www.mapleprimes.com/questions/231603-Solve-Onevariable-Equation
The equation there is quite cumbersome, I extracted a shorter subexpression from it (I converted all floats to exact constants), but the solve command hangs when trying to solve it. fsolve handles the equation easily. We can see that the equation Eq is quite simple and easy to solve even by hand. I ask this question in a separate topic, because this seems to be a serious bug in the solve command.
Edit. I noticed that the isolate command solves the problem, but of course the question remains open with solve .
