AC acting weird

On a normal day with temps in mid 70s to low 80s i can start car and turn ac on and it works fine. Let car sit 8hrs or more with temps in upper 80s to low to mid 90s and get in car ac will not come on unless I rev the engine above 2k to 2500 rpms and it comes on and works fine after that. Not sure what's going on here. Once it starts running it works fine blowing very cold. I attached a can of r134a to low sides port that had a gauge on it, didn't add any, because the guage shows that its charged. Can anyone help me here. 🤔🤷🏽

When this forum search seems to hit the wall, you will find at least 3 AC topics on first 2 pages in this section.
No purpose of starting 1002 topic on the issue that was answered 1000 times.
Do proper troubleshooting and if you can't interpret, post the result here and then we will have some base to discuss.
My crystal ball is down today, so no guessing.
