Slow start-up of shell script extensions

Sorry for placing this message here:

I am trying to post in this thread, too:

https://forum.popclip.app/t/extension-for-gotofile/3332

But I am always getting the cryptic (bogus) error:

An error occurred: You’re replying a bit too quickly. Please wait 4 minutes before trying again.

Too quickly, for what. 4 minutes have passed long ago and several times on top of it. It always comes up with this error…
I am afraid I find this very annoying - now got this error again for trying to post in this thread. This time it complains about being 53 seconds to early…
So the post is somehow on topic, now.
