[RPI4+RPI5] + LE 12.2.0 + TVH 4.3-2433 + hauppauge wintv dual hd (si2168) not working after upgrade

Hello,

The wintv dual seems to be there, but if i try to add muxes, it doesn't work. (DVB-C, Germany, "Privatkabelanlage")
Everything was ok before with the former LE Version.

what could be the reason?`

thank you,

stefan

P.S.: I also tried it with a Pi5, but only got the same result.

I got this when trying to debug:
