"Unable to find specified shortcut" when power on Macbook

Using a Macbook Pro M1 2021

Apologies if in the wrong topic section, i'm unsure where to post this.

Whenever I turn on the mac and log in, the message pops up "unable to find specified shortcut".

I have deleted all previous shortcuts but the message still keeps happening.

Any tips on how to stop it happening would be great.

Thank you!
