I deployed WordPress in Laragon using the quick create > WordPress option. Now after working on the website for a few days. it became inaccessible.

So when I access stleo.dev (that's the site url) it simply gives me a blank page on the web browser.
I've tried all means of fixing WordPress white screen of death but it seams the issue is coming from Laragon as I can not access old WordPress installs but can easily access recent ones.

I really need help with this because I have to deregister a theme in stleo.dev, so as to use the themes license key on the production site.
