LR Error Failed to retrieve linguistic data

For the past few days, I’ve been getting the following error message on Netflix: “Language Reactor Error: Failed to retrieve linguistic data: NETWORK_ERROR Lang:en.”
As a result, I can’t get translations, even for individual words, by clicking on them.
It’s really frustrating!
The message doesn’t appear on YouTube, but I can’t get translations by hovering over words. I deleted and re-downloaded LR, but the problem persists. I know people have asked about a similar error but no answers ade and this problem still happens to me… it makes the app almost unusable … Any solutions?

PS: I’m French living in the US (so I’m learning English as a second language).
