I too have been experiencing this issue. I have a del D6000s docking station i use with Macbook Pro M2 all the time. No issues. I now also have a macbook air m4 and have been unable to get it to work after any sleep action until I restart the machine.

this has been driving me nuts but I now think I have solved some of the problem.

There is a setting on the macbook air M4 that that I have now set and it changes the behaviour of the problem.

Prevent Automatic Sleeping on power adaptor when the display is off. It was disabled and now that I have enabled it my macbook air seems to be recovering display link after suspend.

I have not been through all the scenarios yet.

Sleep time out works.

Sleep manual works.

But if I turn off the power to the dock it will not recover. And a restart is required

So there is something in this but it does not completely fix it

Very Annoying. Not sure why my macbook pro works ok. Exactly same apps and version which is latest 1.12.4 build 90

Before hand it would never recover after sleep unless restarted
