No Conversion Rate Error Message From Metamask

I bought 10 dollars of BRM, and it has now increased to 100 dollars and is still going up. However, I cannot switch to USDC. I keep getting the error message “no conversion rate,” and no graph is visible, nor is there any traceability of either my initial 10 dollars or its current growing value. I am not sure if this is a scam or what is really happening.
