As you have found out for yourself, the new symbolic module is clearly inferior to the old legacy muPad (and muPad was already a big step backwards compared to Maple, which was used earlier). Conclusion: Use the legacy symbolic for symbolic calculations as long as it is still possible and then switch to a more powerful software later.

With muPad what you tried is no problem:

But even with the new catastrophe there are possibilities:

It seems like it's "just" the arg-function, which the new Symbolic can't handle properly:

The "unknown error: index_out_of_range" is rather strange and I would call it a bug.

Needless to say that the legacy symbolic handles the expression without problems:
