Appium Not Running Xcode 12.3

I’m trying to use Appium version 1.19.1 to test an ipad app on a physical ipad device that I have built with Xcode 12.3. Previously this has worked as expected, but recently I have not been able to get Appium to run at all, and I suspect that Xcode 12.3 may be the issue based on what I have discovered.

When I try to run Appium from python this is the trace printed to my python console (device serial number/udid intentionally hidden):

** TEST EXECUTE FAILED **
Testing started. Make sure you follow the tutorial at https://github.com/appium/appium-xcuitest-driver/blob/master/docs/real-device-config.md. Try to remove the WebDriverAgentRunner application from the device if it is installed and reboot the device.

Through researching I came across this answer which linked to an apple developer forum post that leads me to believe the issue is with one of the frameworks that appium must be using that is not cooperating with Xcode 12.3.

I have also come across another suggestion that I tried but it did not fix my issue.

Also, this is what I’m seeing in Test-WebDriverAgentRunner-2021.01.06_17-04-19--0600.xcresult:

  Assertions: System: Failed to install or launch the test runner. If you believe this error represents a bug, please attach the result bundle at /Users/Library/Developer/Xcode/DerivedData/WebDriverAgent-alwvnomvwrdtzoaxbbkniqrpcdpp/Logs/Test/Test-WebDriverAgentRunner-2021.01.06_17-04-19--0600.xcresult. (Underlying Error: The file “WebDriverAgentRunner-Runner.app” couldn’t be opened because there is no such file. The file doesn’t exist. (Underlying Error: The operation couldn’t be completed. No such file or directory))

So is there anything else I can try at this point, or is this going to come down to a framework being used by appium needing to be updated? Any ideas or suggestions are definitely appreciated!
