[Thu Dec 14 19:43:01.002817 2023] [php:error] [pid 35371] [client 127.0.0.1:45634] 
PHP Fatal error:  Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, bool given in modules/Import/views/ImportListView.php:131

Stack trace:
#0 modules/Import/views/view.last.php(189): ImportListView->display()
#1 modules/Import/views/view.last.php(141): ImportViewLast->getListViewTableFromFile()
#2 include/MVC/View/SugarView.php(210): ImportViewLast->display()

#6 index.php(52): SugarApplication->execute()
#7 {main} thrown in modules/Import/views/ImportListView.php on line 131, referer: index.php

Problem only happens with PHP v8, not with v7.4.
