Same issue and setup here - macOS 11.4, iOS 14.6, Xcode 12.5, Safari 14.1.1.
Unable to use the workaround via Safari Technology Preview as the install of STP 125 or 126 gives version errors on each one. (125: "This update requires macOS version 10.15.", 126: "This update requires macOS version 12").
Had to result to using a Mac running Catalina and STP.
