I think the Russian explanation is simple enough and don't believe we have to put tinfoil hat for this. We knew that this would be the result of sanctions on western tech and knowledge. I've met and talked a lot with a Russian/Khazak "oil engineer" (asylum seeker, hosted by my mom) and to be honest, his knowledge in thermodynamics was abyssimal and wouldn't qualify for "system dynamics 201" (loose translation, sorry) in my country. I know there was difficulty with the language but even mathematic objects (tensor specifically, he knew what a matrix was) escaped his knowledge. He was probably a very good plumber and technician, able to repair a lot of mechanical issues (he found work in a garage), but the fundamental seemed very shaky in my western view. I think that if trully skilled workers left, and western monitoring and support are hit by sanctions, any issue like this is very likely to happen on its own and stand to happen more and more as the months pass.
