In Sketch001 where the arc and the upper horizontal are creating an acute edge and creating a convergence issue.
If you apply an perpendicular constraint between these two then al is good.
Although that does appear to resolve the issue , it is doing so indirectly and is not actually the problem.

Am I right that even if I would want to have sharp edge similar to that it will problematic?
All I had to do was recompute the whole document without changing anything and it worked. Update your FreeCAD to the latest dev snap shot of 0.19 since it now has well over 6 thousand bug fix and new feature commits of code. It is way better than 0.18 and there is just no point in continuing with the older version.
As a general rule, you should always fully constraint your sketches, otherwise you have not fully described your object and you are more likely to have these strange issues. Unless you put it there for some other reason, there is no need for the construction circle in this sketch, you could have just directly constrained the arc with a radius or diameter constraint.
