I see what's happening here: your model includes the residue MO6 (a Mg2+ ion with 6 coordinated waters - FYI, this is obsoleted by the wwPDB and shouldn't be used anymore). ChimeraX doesn't really know what to do with this - the magnesium-oxygen bonds are converted to metal coordination pseudobonds, and AddH refuses to add hydrogens to the oxygens. ISOLDE doesn't have any parameterisation for clusters like this - you'll need to model it as a MG with individual HOH residues. If the density isn't great, you'll want to use ISOLDE's interactive distance restraints tool to restrain the Mg-O distances - just ctrl-click on the Mg, ctrl-shift-click on an O, and on ISOLDE's Rebuild tab find the distance restraints widget near the bottom, set the distance you want (and probably increase the spring constant to about 500), and click the add-restraint button. Sorry this is a bit involved - I'm still looking for a better, more general solution to handling metal coordination geometry.

The actual source of the error is that for unrecognised residues ISOLDE tries to use a graph-matching algorithm to match the residue to potential templates, allowing for possible missing or extraneous atoms. The problem is, due to the issues above your MO6 comes out having 7 graph nodes (atoms) and 0 edges (bonds). Not a scenario I'd foreseen, hence the traceback. Will adjust to give a more informative error message in such cases.
