Connecting macbook pro to external keyboard and monitor- only one will work at a time

I have a MacBook Pro (2020) with thunderbolt ports. I want to connect it to an external monitor and keyboard. There is a usb device that came with the keyboard and mouse that I am connecting through a Thunderbolt-multi-USB adaptor. That works when it is the only thing connected. When I also connect my monitor through a a VGA-USB adaptor (using the same Thunderbolt-multi-USB post adaptor), the monitor works, but then my keyboard stops being connected.

How can I use both the keyboard and the monitor at the same time? Do I have to use different Thunderbolt ports? I didn't think I would need to since the Thunderbolt-USB adaptor came with multiple USB slots.

MacBook Air 13″, macOS 10.12

What is the make/model of this adapter you’re referring to?

Unfortunately, inexpensive ones often fail to perform as one would like. Personally, I have a Brydge Stone Pro dock with monitor, keyboard, trackpad, webcam, Ethernet and power all over one TB3 connection.

Thanks for your advice. I did look for less expensive versions of everything. Do you think the VGA to USB adaptor is the issue, or the monitor and keyboard? I just ask because the adaptor would be a cheaper fix.

Here are all the parts involved if that helps- thanks again!

The Thunderbolt to USB adaptor is:

Satechi Slim Aluminum Type-C Multi-Port Adapter with USB-C Pass-Through, 4K HDMI, USB 3.0 - Compatible with 2020/2018 MacBook Air, 2020/2018 iPad Pro, 2020/2019 MacBook Pro (Space Gray)

The monitor+keyboard+mouse that comes with a USB for the keyboard/mouse and a VGA for the monitor is:

Acer SB220Q bi 21.5 Inches Full HD (1920 x 1080) IPS Ultra-Thin Zero Frame Monitor (HDMI & VGA Port), Black

The VGA to USB adaptor is: FrescoLogic FL2000 VGA to USB3
