Here is the [study] (https://www.sciencedirect.com/science/article/pii/S240545772400038X) (N=1.8 million)
Conclusions
This MR study demonstrated no significant causal relationships between red/processed meat intake and the risk of the four CVD outcomes examined. Further investigation is warranted to confirm these findings.

Here is an older study (N=29 682) that claimed to have found correlation between redmeat and heart diseases.
Cholesterol problems seem to arise from many things, from weight to stress to dietary to some extent.
Some people believe (as another poster said) that dietary cholesterol has no relevance to your levels, but I think that is observably not the case because people have actively improved cholesterol levels simply by revising their diet, thereby tying it in at least some fashion.
It's just that, you should eat things that are high in good cholesterol, rather than bad cholesterol. Things that encourage high HDL (such as eggs) is better than things that encourage high LDL, which from what I understand, seed oils can cause.
