That is strange: I do not see much in the log files.
the twelvesevcendytower.log shows 0881H.c4d is being loaded but the log stops just after that and before static mesh are created.
the other one does not show any c4d import.
I successfully loaded on my 4.27.2, around 2 minutes to import the file you shared with me.
maybe @Antoine_Guillo has some ideas?
