为什么 VSC 会抛出此代码的语法错误？

Question

I do not simply ask for advice on why something isn't working as intended, but as to why VSC or my linter (ProSpector) seems to think it is wrong. I'm a little stuck and after reverting my code back to how it used to be, it seems to still show it as an error.

@cmd.add_command(name='addgroup', aliases=['ag',])
def add_group(group):
  if group in mods:
    print(f'{color["blue"]}{group}{color["red"]} is a duplicate. Try something different.{color["reset"]}')
  else:
    mods[group] = []

Something is wrong with this code, and it is not my objects, as they are all defined. This is some kind of syntax error:

Any help is greatly appreciated because I'm so unsure of the issue. In all honesty, it might be VSC messing up, because my code still runs fine, but I really am not sure.

The weirdest part about this issue is that it seemingly has no cause. I have found a fix for it while writing this question and will list it below:

• Cut Code
• Paste Code

Done. Why does this fix this weird persistent error that wouldn't go away when I retype code? I have no clue, but the cut and paste method works, so there we go.
