Any new episode of fiash
I think you meant "Flash"!
As of my knowledge cutoff, there hasn't been a new episode of The Flash TV series since its 7th season finale in June 2021. The show has been on hiatus since then, and there hasn't been an official announcement from The CW or the show's producers about a new season or episode.
However, it's worth noting that the show's future is still uncertain. In May 2021, it was reported that the show's stars, including Grant Gustin, had signed new contracts, but there was no confirmation on whether the show would be renewed for another season.
If you're eager to stay up-to-date on the latest news about The Flash, I recommend following reputable entertainment news sources or the show's official social media accounts for any updates!
