hoping someone may be able to provide some help with resolving this issue, I've been pulling my hair out trying to figure out what's causing the crash. Only started happening this morning. I launch the application, it's does its loading and initializing this and that, then bam .. both blank screens and not responding, just an application hang with no errors. as seen in the screenshot below.
I've uninstalled and fully removed all traces of the application including registry entries, even tried rolling back to 11.1 but have had 0 luck :( When I installed 11.1 it loaded up the messages window but a huge loopy spam error was appearing, some internal self test error .. I didn't get a chance to screenshot it unfortunately. Hoping someone might have some sort of solution or fix I can try. Thanks

Many program problems can be resolved by resetting Mathematica's configuration. Can you please try removing or renaming all these folders:
• C:\Users<user>\AppData\Local\Wolfram • C:\Users<user>\AppData\Local\Mathematica • C:\Users<user>\AppData\Roaming\Wolfram • C:\Users<user>\AppData\Roaming\Mathematica • C:\ProgramData\Mathematica
