'Adding php 7.4 to wamp server 3.2.8

I'm trying to add PHP 7.4 to WAMP server , I already added PHP 7.4 add-on, but its not showing in the list, i tried all solutions I found, but no use, I get this error in php_error.log

#0 C:\wamp64\scripts\refresh.php(132): DateTime->__construct('\xD9\xA2\xD9\xA0\xD9\xA2\xD9\xA2-\xD9\xA0\xD9\xA4-\xD9...') #1 {main} thrown in C:\wamp64\scripts\refresh.php on line 132

and in apache error log I get this error that does not make sense to me:

wamp apache error

any help will be appreciated :)



Solution 1:[1]

Since there are no answers, I just uninstalled WAMP and deleted WAMP folder from c: / drive completely after I backed up my sites and database, and reinstalled it, and this fixed the issue.

THANKS ANYWAY
