Hello,
I am unsure as to the root cause of your issue, but we could certainly troubleshoot this remotely, I have access to a Bomgar remote support appliance that could facilitate the remote support with ease.
We would ideally start with a few steps, attempt to rename or clean any folders in the user profile associated with Discord, attempt to remove all of the registry settings for Discord under the current user. Attempt a removal of the application, search for remnants in the registry, remove any configuration files that may exist, remove any application files that may exist, and attempt a reinstall of the application. I was unable to find any information posted publicly with the error code as stated.
I am an expert problem-solver and have been working with various operating systems for the past 30 years, and there isn't much that I can't solve. I work Monday to Friday, 9-5 EST, but available outside of these time windows.
