Shortcuts bug or not?

Can any of you Level 10 brainiacs out there PLEASE confirm that what I am experiencing in Shortcuts is a real issue , or is it just me?

I have made several Community posts on this and get no response.

For nearly 9 months now, there has been a change in Shortcuts that slows it down to an unworkable state.

I am guessing it changed with an OS update.

I had before a simple 1 step Shortcut on my desktop to open PDF's from my HD.

One action 'Open File', thats all!

Now that Shortcut takes about 2 minutes to open a 200mg PDF, whereas, if you click the same file to open via the Finder, it opens instantly. This is what Shortcuts used to do.

PLEASE, brainiacs out there, create a Shortcut with 1 action, Open File, select any large PDF and test this Shortcut to see if it works for you, then I will know that it is not just me, PLEASE!!!

PS: I have been to an Apple Store Genius Bar with my laptop and demonstrated the issue to an 'expert' there. They had no answer other than 'that is not right'!!!
