As of 5/21, a new version was released (1.2.0) which supports Apple Silicon & Intel Macs now. You'll be able to install that.

As of 5/21, Asix released another new version: 1.2.0. I was able to install this one no problems on an Intel Mac- don't have an M1 to test it on, so I can't speak to that. I have a problem with IOInterrupts rendering ethernet useless; however, this maybe due to my specific device as it's notorious for ethernet issues across all OSs.

I have the same issue. I found in Console it's called IOInterrupts. I had thought this issue was unique to my device only. It's interesting that those who didn't download the driver manually & had it automatically install upon updating to 11.3 have it working just fine.

spctl kext-consent add 5RHFAZ9D4P This will not work from within MacOS. You must do it from Terminal in Recovery Mode. The same goes for remove, enable, & disable for spctl kext-consent. However, this is completely unnecessary for the full release (the beta versions required it which is why this thread mentions it). After that "___ can't be opened because Apple cannot check it for malicious software" popup, dismiss it & to go to: System Preferences -> Security & Privacy -> General -> Allow. If you don't want to do that every time you download a dmg off the internet: Terminal -> sudo spctl --master-disable -> enter your password & press enter. As @zrt1992 mentioned, there's a new version (v1.3.0) that came out on 8/25, so you should download & install that instead of the one you already downloaded.
