I think it was kind of the reason. But that statement is also correct. Technically.
With CP2077, they were pushing the Red Engine well beyond what it was supposed to do. Which lead to both, them deciding to switch to Unreal, and causing a bunch of bugs. So the bugs weren’t the reason; They were just another result of the reason.
It might be the part of it, but other (maybe main) reason is probably the fact that they had significant crunch culture going and high turnover. They supposedly had trouble recruiting at some point due to running out of interested game dev programmers in Poland. And why take months to train recruits to use your in-house engine, that also requires a lot of work and resources to maintain, when you can use one everyone knows and do simple onboarding.

That’s just semantics.
