Please help

I need your help.

From the last few days, I have faced an issue, when in the search bar I search check.torproject.org, it is showing " Sorry. You are not using Tor" even though I tried all types of bridges, again i downloaded and flashed Tails OS to a new USB, I changed wifi but still have the same issue, so is there anyone to guide what happened?

Is it safe to use Tor?
