Had the same issue as soon upgraded to the newest version. Here is part of WP error log
Error message: Uncaught Error: Failed opening required '/html/businessdirectory/wp-content/plugins/ac-advanced-flamingo-settings//vendor/autoload.php' (include_path='.:/opt/remi/php83/root/usr/share/pear:/opt/remi/php83/root/usr/share/php:/usr/share/pear:/usr/share/php') in /html/businessdirectory/wp-content/plugins/ac-advanced-flamingo-settings/ac-advanced-flamingo-settings.php:38

I solved it by downloading 1.30 from here: https://plugins.trac.ww.wp.xz.cn/changeset/3268306/?format=zip&new=3268306 and then I copied the complete ‘vendor’ folder and the file ACAFS_Background_Import.php into the lib folder –> now I could activate the plugin and everything works.
This issue has been resolved in the subsequent release. Thanks for your patience. Note to self, do try and release stuff at Christmas!
