WinExtras JumpList does not work

[Allstar12345]

Not managed to find any issue on this one yet, for some reason I'm not able to get QWinExtras JumpList to work (other winextras modules like ThumbnailToolBar work spot on).

Using Qt 5.15.2 on Windows 10 20H2, but this has occurred for a while (both 32 and 64 bit effected, )

Basic code like this crashes and gives this message after a second try:

 JumpList {
       id: jumpList
       recent.visible: true
       frequent.visible: true
   }

FTH: (12772): *** Fault tolerant heap shim applied to current process. This is usually due to previous crashes. ***

Trying something like this gives me the error below:

   JumpList {
              JumpListCategory {
                  visible: true
                  title: "Test"
   
                  JumpListLink {
                      title: "Test Link"
                      executablePath: "http://google.com"
                  }
              }
          }

QWinJumpList: AppendCategory() failed: 0x80070005, E_ACCESSDENIED.

Oddly a c++ jumplist works from main() but it's QML functions I need to use.
