Solution 2: Add Discord Installation Files to the Whitelist of Antivirus Software

Sometimes the antivirus that we use in our computer protect our data against the virus or other unwanted threats. But sometimes these antivirus programs tend to block the programs on our computer and Discord can be one of them as well.
The conflict between the antivirus programs or application and the Discord can be a reason behind the Fatal Discord Javascript Error.
