Problem launch .aex script on Mac OS

Hello,

Running After Effects 24.4.1

Mac OS 12.7.4

Tried to install a .aex script that worked well on past version but now each time I launch After Effects with this script in the Plugins folder, I get the warning window about security problem due to unknown developper. Usually this can be solved in the System preferences panel by forcing to launch but this time it does'nt work.
Any one knows how to solve this ?
Thank you by advance.
