Ok I have found the source of the problem, the OpenMeteoParser when reading from the URL is adding an extra } at the end of the code therefore making the widget search for icons and descriptions that doesnt match. If someone has any idea of how to remove that extra symbol at the end of the string would make everything run as normal.

Temporary Fix
Open the following files with notepad:
My Documents\Rainmeter\Skins\Monterey@Resources\Languages\en\Widgets\Weather.inc

• There are 4 folders inside Languages: de (deutsch); en (english); ru (russian); ua (ukrainian); open the one according to your settings selection.

My Documents\Rainmeter\Skins\Monterey@Resources\Scripts\Widgets\Weather.inc
Make a copy of the orginal files as a backup in case something doesnt work.

Inside the file on languages you need to find the lines containing tWeatherCode and add the symbol } after each number as seen in the image below:

In the file in the script folder you need to find the section titled [Variables] and under IconName add the symbol } after each number as seen in the image below:

Go to Rainmeter and update the skin and it should all be working fine now until the skin is properly fixed in the future.
