I am encountering the

Termination Reason:    DYLD, [0x4] Symbol missing

error when attempting to run 3.6.9 stable on Big Sur. The recommendation here is to upgrade to sonoma, but for reasons of other software I cannot upgrade without breaking critical software. Is have not been able to find any earlier .dmg files, I was hoping to install the lastest version that remains compatible Big Sur. Is there a repo to try, a binary package of say 3.6.7?

(additional information from the error for reference, it has been discussed elsewhere in the forum without resoultion but to upgrade as far as I can tell)
Application Specific Information:
