"Can't get Screen Sharing to work Since Big Sur 11.2"

Troubleshooting this:

A. Reset the SMC and your NVRAM:

Sometimes when changes are made to the system(i.e. updates), system configurations (i.e. for screenshare become manipulated, technically. So, reset the SMC and NVRAM. It might take up to three tries to reset both successfully. So, be certain you have the time to do so.

B. Try a New User:

Create a new user (for troubleshooting purposes) - see if it still happens. If so, then it is something created in your current user.

Also...

C. Screenshare with Apple Support:

See what happens when you contact Apple Support, and request to perform a screenshare (for troubleshooting purposes, just to see if it works). If it works, then it is likely something to do with the Application you are using this with - and the developer has yet to do their part in getting it all to work with the macOS.

Contact Apple Support:

• Contact Us - Choose Locations
• U.S.A. (800)MY-APPLE
• Proceed from there as necessary

Note: Phone calls are taking a bit to go through at the moment, due to lots of calls. With the Coronavirus Pandemic, many are at home at the moment, with much time on their hands to contact Apple. So, just stay on the line, and you will get through :)

For some, turning off screen sharing, restarting and then turning screen sharing back on solved the problem.

Personally I've have not had any screen sharing issues, but the difference might be because I'm sharing over my local Ethernet network instead of a Wi-Fi network.

You are welcome. Let us know how it works out.
