Same issue with two latest versions of Nvidia drivers, with both bundled and separated JRE, with not elevated and with elevated rights, with and without active Defender and Firewall, stable and beta launchers, in all combinations of previous mentioned software and conditions.
It don't create any crash reports, game freezes at application loading, and it is definitely caused by launcher or by game builds.
The only log the launcher and application are producing is the launcher log. And the game in this log was terminated, because launching time what takes several minutes plus (to infinite) is unacceptable.
Also note another major bug, what log's timestamps are incorrect and don't match system time.
I can get to you javaw's 2.3 GB dump for you to analyze, but i guess your workflow isn't designed to go that deep analyzing way.
Lets go through that "MCL-6550":
1) _JAVA_OPTIONS - not present in the system
2) Discord is not installed
3) None of "Incompatible software" is installed
4) Using any third party "Cleaners" is a very bad move. I am regularly checking my setup with Fortinet, Paloalto and other big and trusted vendor solutions with none of them in permanently installed state in the system.
And last - I am asking to elevate ticket to the second tier of support or higher.
