DVBViewer Client couldn't be installed



Hi,
I installed Kodi 21.1 on a new Fire-TV 4k.
I’m restored the data of my shield Kodi.
Everything works, except PVR. I’m not able to get the DVBViwer Client installed.
It was restored, but not activated.
Tried different versions from github pvr.dvbviewer/releases
Error message in Debug Log:

Kodi Debug-log:
error <general>: CAddonInstallJob[pvr.dvbviewer]: invalid package special://home/addons/packages/pvr.dvbviewer-21.1.2.zip

Other PVR Clients couldn’t be installed, too.
Has anybody a solution for this problem?
