Unable to serialize value. Error: Malformed UTF-8 characters, possibly incorrectly encoded

Hello guys.

 

I just installed Magento 2.3.2 on my local MAMP server, with composer.

Installation is completely clean. I do nothing yet.

The problem is - when I trying to configure Extension Manager after put my keys and pressing submit button I have this error message -  Unable to serialize value. Error: Malformed UTF-8 characters, possibly incorrectly encoded.

 

Please help me with this problem
