@masagrator that can be fixed by changing line 21:

def do_SetName(arg1, arg2):

to

def do_idc_set_cmt(arg1, arg2):

I did it and now I got error:

Traceback (most recent call last):
File "C:\Users\Marek\ghidra_scripts\ildumper_script_reader.py", line 68, in
res = globals()['do_'+name.replace('.', '_')](arg1, arg2.replace(' ', '-'))
KeyError: 'do_SetName'

I've managed to do it different way.

added

def do_idc_set_cmt(arg1, arg2):
return

https://gist.github.com/masagrator/f21a0bb7b882b509c34beba7d2258b5d

it's working with 5.0.4
SetName and idc.set_cmt are almost the same thing, just idc.set_cmt has sometimes additional line for I don't know what. :P

Two examples

SetName(0x3ECACE0, 'Class$List<MAUUIAnimation>')
idc.set_cmt(0x3ECACE0, r'List<MAUUIAnimation>', 1)

doing the same thing

SetName(0x3ED4B78, 'Method$ContextAttribute.IsContextOK()')
idc.set_cmt(0x3ED4B78, 'Method$ContextAttribute.IsContextOK()', 1)
idc.set_cmt(0x3ED4B78, '0xB7D9A0', 0)

first two are doing the same thing, third line is doing something extra
