Hey! I have been getting errors when I try to use lives previews on a SwiftUI project. It even happens when I create a new one from the SwiftUI template.
This is the error message:
RemoteHumanReadableError: Failed to update preview. Error encountered when sending 'display' message to agent. Edit: Where should I upload the diagnostics report file?

Hey!
It is my second time asking for this recurring issue. I just downloaded Xcode 12.3, macOS 11.1, and iOS 14.3 on my device, and I am still getting the same error when I try to preview on my connected device:
RemoteHumanReadableError: Failed to update preview.
Error encountered when sending 'display' message to agent.

Did find:

I even try with a blank SwiftUI project, and it is the same error message when I run a live preview on a device (Static previews, live previews, and build/run on device work fine).
I found some other people on the forum asking for the same bug, but none of them had answers to this problem.
I am running out of ideas on how to solve it, but I noticed that on line 8, it says ...7FF//tmp/..., while on line 9 says ...7FF/tmp/.... Not sure if it helps.
