“AW snap” error can also be caused by the PWA Plugin

Hello.
I installed WordPress for a client’s website, and everything was okay at this point.
I bought and installed a nice WordPress theme, and everything remained okay.
I imported a demo for the theme I had installed, and I was prompted to install some plugins.
As soon as all required plugins were installed and activated, one problem arose.
Whenever I try to open “Pages” or “Posts” from my WordPress dashboard, I get the “Aw Snap” error.
Of course, I did what a regular developer will do – I searched the internet for solutions, but all the solutions that I found did not solve the problem – for instance, clear cookies and cache, reinstall the Yoast plugin, etc.
So I was on my own.
I deactivate all the plugins and the opened the WordPress “Pages” in another window and alas, it loaded without the error.
So reactivated the plugins one at a time, going back to refresh the window in which I had earlier opened the WordPress “Pages” after each plugin was activated.
It took quite a while to run through all 19 plugins, with a slow network.
Each refresh of the “Pages” window was successful.
Until I activated the Progressive Web Applications (PWA) plugin (plugin contributed by PWA Plugin Contributors).
On refreshing the “Pages” window after activating PWA, the “AW snap” error returned.
And when I deactivated PWA plugin and refreshed the page, the error disappeared.
I could not find a direct solution to the issue – so since my website could stand without the PWA plugin, I continued without it.
If anyone has a solution, kindly share.
