M-. takes over my commands and can't execute OR C-g to escape

Question

I am using Emacs 26.3 and trying out ggtags-company-mode to navigate my code base.

I move my cursor to a function I want to jump to the definition of, poll_count, and enter M-.

I now have this at the bottom of my session in the minibuffer:

But when I try to tab to it (I have ido-everywhere), It inserts an actual tab:

So I hit backspace to remove the TAB and hit RET. But now it inserts a literal RET:

I want to /select/ this not insert a literal enter. So now I want to give up, and I type C-g to cancel this command in the minibuffer:

It says quit, but then comes right back to:

It does this no matter how many times I hammer C-g C-g. So now my editor is stuck here and this is my life now. I can neither escape the command to terminate it with C-g, nor execute it with TAB or RET.

For what it's worth, the poll_count function is defined just a few lines above in the same file, so I didn't expect this to be such a trap.

Update

C-] and ESC ESC ESC both cancel the command OK, so I am not trapped in the minibuffer forever, but I still can't seem to select the Jump to: target correctly.
