While CRT is kept deliberately nebulous, as others here have pointed out, there are some underlying assumptions that can be pointed out:
1. Any "criminal action" committed by a POC is a direct consequence of environment, and that environment/circumstance, is something created by the oppressive "other". That "other" is whiteness/white people. The consequences of this are a) the "fault" here lies with the oppressor, b) the action cannot be considered criminal
Now if you say that to someone who espouses CRT, they will scream it is a distortion. But then ask them questions regarding black-on-black crime, and see how fast they start framing things in relation to white power structures and systems of oppression. Through every circumlocution, they will affirm the point above, and not even know it.
When the BLM buses showed up in my city, dudes poured out and started looting and burning, assaulting people, etc., anyone who complained about it was asked to "check their privilege", or to understand how their own racism contributed to this "rightful rage". Again, white people are responsible for the burning of their own cities.
2. Systemic Racism is not something proven through empirical or logical means. It is always assumed in hindsight through "de facto" reasoning. Less black were admitted to a school than whites? The explanation has to be racism. More blacks in jail than whites? It is impossible that blocks commit more crimes --has to be racism.
3. White people of every background and ethnicity are thrown into one big entity called whiteness, and that supergroup is directly responsible for every human evil and system of oppression. The dehumanization of this group is a hallmark of CRT, and is historical. The Hutus dehumanized the Tutsis, Nazis the Jews, Bolsheviks the Ukrainians, etc. There is always a group out there that needs to be targeted because it has special privileges and rights, and because it is fundamentally evil
There are many other aspects to CRT, but the most important things are the political, ideological, and rhetorical objectives of the movement (it really isn't a school of thought, it is a movement). Those are revolutionary: the overthrow of capitalism, destruction of whiteness (white people), and the dictatorship of POC.
Now it should be said that Derrick Bell, the guy who basically created CRT from Neo-Marxism / Critical Theory back in the 1980s did not foresee or understand the full implications of where he was going with all of this. He once said:
"Power in the hands of the reformed is no less corrupting than in the hands of the oppressor"
So what happened? Well white women got a hold of this (Peggy McIntosh and others), and it became more radicalized. Black activists seized upon CRT without fully understanding the original ideas and began generalizing them, twisting them for specific purposes, etc. Much in the same way that Mao admitted that he didn't read much Marx or Lenin, wasn't any kind of Communist scholar, but that didn't matter. He was out for practical results.

Guys, no one is obligated to consider or respect such a pernicious and irrational system of thought / movement. I have been at gaming conventions drinking with fellow attendees when some dude starts going into his CRT platform, expecting that others will nod in agreement. He is shocked when I countersignal him hard, and begin shutting down his irrationalism and ignorance on the spot.
As a former college instructor (previous life --never again!), you just don't get to say a bunch of stupid shit in front of me and expect me to go along with it. Expect to be challenged.

And we know that in gaming, CRT has made big inroads in subtle ways. White characters, ethnic groups, and cultures are erased from books, supplements, or whole systems. Slavery becomes a forbidden topic. "Alternative" lifestyles are celebrated. Gaming companies signal hard on every "progressive issue" --and all of this is mostly out of fear.
