Premiere 23.3 and 23.4 - Copying multiple clips takes too long

Copying (with Cmd+C) multiple 4K clips in a timeline takes a very long time in Premiere 23.3 and 23.4 before the process completes.   After testing the same project in 23.2, 23.3 and 23.4 (on Intel macOS Ventura), hitting Cmd+C on multiple 4K clips (1h long selection) take 2-3 minutes in 23.3 and 23.4 and is instantaneous in 23.2.

Please fix this in the next update
