Overview with distinction of searchable/non searchable PDF files

I am looking for a tool/approach that delivers me an overview of all PDF files with a marker that illustrates if PDF file is searchable or not.

What I am thinking of at first glance is a file manager that supports this feature.

Explanation:
I have lots of PDF files, some of them are searchable, some not.
I want to get an overview of searchables/non searcables, not by opening each file manually and check if its searchable.

The main goal behind this question is that I have lots of pdf files and I want to make them all searchable but to do that I first need to have an overview of which pdf files are already searchable and which not.

Is there a tool that can do this for me? Or an easy/quick approach as an alternative?

Thanks,
Mathijs

php – PDF file randomly breaks upon upload

The issue randomly started happening. When I upload a PDF file via the media library, it sometimes ‘adds’ random lines and graphics to the PDF file(or solid brown color), but sometimes it is okay.
WP core is updated to latest, plugins as well, php is running 7.3.
I wonder if it is ever WordPress issue or a hosting issue.

What could be the reason?

EDIT:
here’s the list of the plugins:

Abandoned Cart Lite for WooCommerce
Advanced Custom Fields PRO
Advanced Order Export For WooCommerce
Contact Form 7
LionScripts: IP Blocker Lite
Mouseflow for WordPress
MultiLine files for Contact Form 7
NotificationX
Post SMTP
Really Simple SSL
SVG Support
WooCommerce
WooCommerce Order Status Control
WooCommerce Order Status Manager
WooCommerce Stripe Gateway
WP Cerber Security, Anti-spam & Malware Scan
WP-PageNavi
Yoast SEO Premium

Which one has a chance to be the villian?

for ($i=1; $i<count($sheetData); $i++)
