Systemic network bug (net_error -200) in Chrome/Edge Flatpak breaks WhatsApp Web, Canva, and Facebook

Hello!

I am experiencing a severe and persistent issue when using Chromium-based browsers (Google Chrome and Microsoft Edge) installed via Flatpak on my system. Initially, the issue seemed restricted to WhatsApp Web (where the QR Code stays in an infinite loading loop and phone number login also fails), but I have noticed that the failure is systemic and is breaking multiple productivity tools and social media platforms.

Observed symptoms:

WhatsApp Web: QR Code stuck in an endless loading loop and refusal to validate sessions.

Canva: Inability to save design progress or export files. The website displays saving errors and freezes when trying to process downloads.

Facebook: Constant failures when trying to create or save posts (posts and photos disappear or get stuck loading indefinitely).

When running the affected browsers via terminal to inspect network behavior, I noticed that the Chromium engine fails to perform the security handshake (SSL handshake) with the servers of these platforms. Here is the error log generated in the terminal:

[80:94:0811/194434.343626:ERROR:net/socket/ssl_client_socket_impl.cc:978] handshake failed; returned -1, SSL error code 1, net_error -200
[80:94:0811/194434.343813:ERROR:net/socket/ssl_client_socket_impl.cc:978] handshake failed; returned -1, SSL error code 1, net_error -200

No source file, test, or reproduction command is provided. Start by reproducing the Chrome/Edge Flatpak failure from a terminal and inspect the reported SSL handshake error (net_error -200) across WhatsApp Web, Canva, and Facebook; done means the affected sites connect and function without these handshake failures.
