ASP.NET Version string portion was too short or too long. (Plesk)

So i have a website that i uploaded on plesk a couple of months ago, the website was working perfectly, until a couple of days ago it stopped and showed me the error of (Version string portion was too short or too long.) for absolutely no reason, I did not touch the code, I did not alter the web.config file, the error just came out of nowhere.

So far I have been looking for a solution and nothing has worked for me, I do not know the source of the problem, I'm using ASP.NET version 4.8 , is the problem related to the web.config file? or the sql database? I really have no clue.

Here's my web.config file:

    <?xml version="1.0" encoding="utf-8"?>
