This situation happened to me too. I just downgraded my mac from tahoe to sequoia. I didn’t have the strength for all the incompatibility issues

Learn why this is important at https://aka.ms/LearnAboutSenderIdentification ] Dear Amir To get CCP4i1 and old-coot to work on a Mac with Apple chip (M4 Max) running Tahoe 26.2 I had to install a Linux virtual machine with Rosetta and Apple Virtualization. I went with ubuntu-25-10-desktop-arm64.iso using UTM. Gemini was a big help as I had to play around with various things/settings. Hope this helps.
