While examining this topic, and commentary about it, I am prompted to suggest that we are allowing the use of specific WORDS and concepts to interfere with understanding and that we might be better served to remove and eliminate dependence on and use of the word "race" in this discussion.  My thoughts:

A discussion of "Critical Race Theory" by Encyclopedia Brittanica states six primary hallmarks of this social concept and I find that I can agree with all of them EXCEPT the first one - that "race" is a social construct and not biologically determined.  https://www.britannica.com/topic/critical-race-theory

I disagree with that idea in that it is CLEARLY OBVIOUS that there ARE large groups of people who resemble each other biologically in significant ways and differ biologically from other large groups in significant ways - something that we have labeled "race".  But these biological differences, we have learned over time, are much more superficial and insignificant than what we all, as humans, have IN COMMON.  What, in fact, we might better identify instead of "race" (visible or biologically differing characteristics) is the way we have socially treated one another.  In this regard, I suggest a term - Social Group Bias - as more fitting to describe what we have been accustomed to calling racial discrimination.

Yes, it is definitely true that the more glaring examples of Social Group Bias are very strongly associated with biological differences and are certainly (to a degree) related to those differences superficially.  But our persistent Social Group Bias is also evident between groups that are NOT distinguished biologically - such as between ethnic groups (as in the historical initial bias in America against the Irish or the Italians).  It is also to be seen between affluence levels, even within "race" groups - reciprocal bias between the rich and the poor.  And within ethnic groups as well (intolerance and bias between Asians or Hispanics of different national origin, for example).

My point is that what we are calling a "race" problem is really a MUCH BROADER problem of culturally perpetuated Social Group Bias that is, in part, a NATURAL response to the problems of dealing with OTHERS - those who do not look like us or come from our social and historical origins.  Historically, every dominant majority has dealt with groups of people who are NOT the majority by using methods of control, exclusion, intimidation, violence and unfairness in order to remain in majority control.  The Founders of our country were not free of this themselves BUT they DID create a Constitution that for the first time clearly attempted to deal with and eliminate the legal and social differences between us.

As others have pointed out - by continuing to harp on RACE, we make it HARDER to accept and adapt to our VISIBLE differences - which have little or nothing to do with who we really are.  By refocusing our attention onto the REAL problem - bias and discrimination against other Social Groups just because they differ from us or threaten our "dominance" - we can, I believe, make more progress in understanding that bias and learning to eliminate it.  The United States of America has the opportunity, based on the concepts in our Constitution, to realize the first nation in history that truly offers EQUAL treatment and opportunity to ALL.  But we have to WORK for it.  And standing in our way is the problem of systemic Social Group Bias that is rooted in our fear of "others" and our natural survival reactions to protect ourselves and those "like us" against "them".  When we learn, finally, that there ARE NO "OTHERS" and that we are, truly, ALL ONE - with varietal differences - we can release that fear and live in peace with one another.
