You need to clean out the screen on the faucet.
At the opening you should be able to unscrew the end of the faucet.You may need a pair of pliers with a rag so you do not damage the end, to loosen it up. Inside is a screen which just needs the clutter cleared out.
This is typical when you do work to water lines and systems.
You may need to check them all.
Easy DIY.
