wamp local backup stuck on loading but can reach rest/v11/help

Hi. I've reached an issue where the backup I'm trying to set up on WAMP gets stuck at the 'Loading...' screen and never reaches a login.

If I add /rest/v11/help to the address I can reach the help page. 

I've tried to include the relevant information below, if I can provide anything else to troubleshoot with or if anyone had any idea what I've missed, I'd be grateful.

PHP Version: 7.4.9
Apache Version: 2.4.46
MySQL: 5.7.31
Elasticsearch 7.13.2

I tried the sql query PK suggesed re: Sugar Identity Service but got "0 rows affected." https://sugarclub.sugarcrm.com/dev-club/f/questions-answers/4939/wamp-local-sugar-from-backup-404 

.htaccess - added file suggested by Jeroen - https://sugarclub.sugarcrm.com/dev-club/f/questions-answers/4939/wamp-local-sugar-from-backup-404 
Amended  "RewriteBase / " to point at  "RewriteBase /sandbox-westlindsey-S11-v2"

httd.conf shows:-
LoadModule rewrite_module modules/mod_rewrite.so

re: http://cheleguanaco.blogspot.com/2014/02/sugarcrm-troubleshooting-sugarcrm-7.html 
I added to httd.conf :-


<Directory "/www/sandbox-westlindsey-S11-v2">
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
Allow from all
</Directory>

I've give full access / modify to the root folder for all users.

sugar_sidecar.min.js?v=1jvUPT-nuueyTTfNEQfQhQ:2043 singleSpa.start() has not been called, 5000ms after single-spa was loaded. Before start() is called, apps can be declared and loaded, but not bootstrapped or mounted. See https://github.com/CanopyTax/single-spa/blob/master/docs/single-spa-api.md#start

Also, there's nothing in the sugarcrm.log or the php_error.log

Thanks again
