I don't see anything that really stands out, but can you confirm that "NGINX" (web server) was installed intentionally?
Also, check that same screen for memory usage the next time that error message pops up. For example:
Runtime Broker is a Windows process in Task Manager that helps manage permissions on your PC for apps from Windows Store. It should only use a few megabytes of memory, but in some cases, a faulty app might cause Runtime Broker to use up to a gigabyte of RAM or more.
