Can't run forge installer

[Arsenicoza]

Hello I have been in a predicament recently while trying to install forge. I have installed forge multiple times before and not encountered this issue that just started a few hours ago.

Some background info:
OS: Windows 10
Java version: latest
Java is set to open jar files

What I've tried:
-Jarfix (multiple times)
-Uninstalling java/ reinstalling
-Updating java
-Installing/uninstalling forge installer multiple times  
-deleting previous versions of forge in files
 

Helpful info maybe:
Whenever trying to open the installer a log is made:

I'm not to good with tech so sorry if this is really easy to fix and I'm just incompetent.

If you need any extra information I'll try and get it for you. Thanks heaps!
