I just wanted to follow up and let you know that we were able to reinstall 2.34.1 properly, and things seem to be working fine. We’ll hold off on 2.35.0 until those issues get worked out. Thanks so much for all of your help.

I also had the same problem with the version 2.35.0 and R 4.2.2:

```R
Error in !is.null(csv_contents$metadata$save_warmup) && csv_contents$metadata$save_warmup : 
  invalid 'y' type in 'x && y'

```

Updating R to the last version (4.4.1) solved the problem

I can confirm the same result for anyone having the same issue.

You likely need to upgrade your version of cmdstanr

No I did upgrade Cmdstsnr but the additional update of my r version was needed overcome the issue
