[Launcher Closes after clicking login]

For me and a community of friends, After we enter our usernames and passwords, the launcher closes and an error file appears with "Close 
Log - 20"

What does this error represent and how do we go about fixing it 

I have tried contacting discord support and haven't been getting a reply.

 

Error is as follows

 

System.AccessViolationException
Message : Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
StackTrace :    at LFS.Memory.ReadMemory(IntPtr address, Byte[] buffer, Int32 size)
