LingQ importer extension doesn't work properly

Yes, I do have the latest update, and I saw that the google extension wasn’t installlable.
I use the one from the microsoft store. Reinstalled it once more and imported some text. This once worked out, don’t know for how long. Everytime I reinstall, I get one or two imports, then it wont open.

Also there was another update for my browser yesterday evening, so once I get the chance to check it out, I will get back to you
