Yes, I’d like to look at this issue. You can send login details to hello@pagespeed.ninja. Do you use 3rdparty caching plugin or other plugins that might conflict with PSN?
Could you post (or send to hello@pagespeed.ninja) URL of your website? It looks like a conflict in javascript merging, but it’s hard to be sure without looking at website’s page sources.
Do you have related error messages in PHP’s error_log file? Usually error 500 is accompanied by such a message in error_log with related filename and line number.
Usually large PageSpeed Ninja’s cache size means there are unique (i.e. varied from page to page or even randomly-generated) inlined javascript or css codes on pages of your website. The solution is to disable “Merge embedded styles” and “Merge embedded scripts” in Advanced tab settings (by default these settings are disabled in “Safe” and “Compact” presets) and then run “Cache: Clear All” in the “Troubleshooting” section.
Did you remove mentioned wp-content/advanced-cache.php file?
This message is not generated by PageSpeed Ninja, most likely it is generated by other optimizing plugin on your website. If you like to use PageSpeed Ninja with another caching plugin, remove mentioned advanced-cache.php file, disable Caching in PageSpeed Ninja’s Advanced settings (“Reduce server response time” section), and enable caching in your favorite caching plugin.
Как правило это связано с тем, что на каждой странице есть уникальный js или css код. Решение в этом случае – отключить “Merge embedded styles” и “Merge embedded scripts” в Advanced настройках (по-умолчанию они отключены в пресетах Safe и Compact). Со временем папка /s сама очистится (через время, в 2 раза большее указанного в настройке “Caching time-to-live”), хотя можно это немного ускорить, запустив “Cache: Clear All” в секции “Troubleshooting”.
PageSpeed Ninja contains its own page cache (see “Reduce server response time”->”Caching” option in the Advanced setting), and if it is disabled, then it should be possible to use any other page cache plugin.
It is AdRotate that generates unique js codes.

What is URL of your website?
Some plugins inserts javascript codes like
<script>var current_url='https://yourdomain.com/current-page-path';</script>or even
<script>var current_time=1564577645;/*current unix epoch time*/</script>and this code varies from page to page, and so results in unique merged javascript file for every page.
22Gb iss too much for static cache. I guess you have some inlined javascript code that varies between pages (or even between users) that results in a lot of unique one-time files in cache. In this case it is necessary to disable merging of embedded javascripts and stylesheets (css).
It’s known issue that will be fixed in 0.10 release.
PageSpeed Ninja compares original score for specified item and current (optimized) one, and color of the switch depends on the their difference. Green: Improves the score. Orange: a minor or no effect on the score. Red: negatively affects the score. If you see red switch, you can either turn it off, or tune related settings in the Advanced tab to get higher score.
