Adobe Acrobat Reader DC can´t open 3D-pdf anymore

Recently I can´t open a 3Dpdf (that is generated via Adobe Acrobat Pro + Tetra4D) with Adobe Acrobat Reader DC anyomore. I get an error message telling "A 3D data parsing error has occured". There has been an updated recently to Adobe Reader to 2021.007.20091 (I don´t know if that has anyting to do with it?). Can you advice, please?
