You have several errors about syntax in the Drawing Dimensioning Addon, the Fasteners Workbench, KiCADStepUP, and Part-o-Magic.
The Drawing Workbench is obsolete, so you shouldn't be using the Drawing Dimensioning Addon at all. Use TechDraw.
The syntax problems sounds like you are using Python 2 but some addons only support Python 3. You should not be using Python 2 because it is obsolete.
You really need to paste the information in Std_About to know more about your system. Remove all addons and install them again one by one until you identify one that is causing the problem.
Also, please notice that KiCADStepUp is an external workbench; therefore, you should ask the author of that workbench first if you have a problem with it. This addon is not maintained by the core FreeCAD team; none of the addons are. Their individual authors should be responsible for providing support in case something doesn't work right.
