There is no need for external CH3XX drivers on the Mac - they have been built-in for several years (Catalina, if I recall). I have attached my Roly Lasermatic, which uses the CH340 chip, on each of MacBook Pro with an Intel chip, my MacBook Pro M1, and a Mac mini M4, all without instaling an external driver. All work flawlessly.
Typical issues:

Wrong type of USB cable - the usual suggestion is to get a USB3 to USB3 adapter, as some devices have issues with USB3 cabling.
Wrong serial speed, configured in LightBurn.

Try the cheapest USB2.0 hub you can find between the laser and the Mac.
