Upload Blynk library arduino impossible

I am trying to update my blynk library. When I select version 1.0.1

then I click on update, this is what is displayed

when I download the library and import the zip folder, this is what is displayed

do you have a solution to fix the problem?

I have already tried to install and reinstall them, but I still have the problem

Just delete the Blynk library folder (documents/arduino). And install a fresh copy of it.

I tried but this message is still displayed : Could not find boards.txt …
is that a problem?

It’s a problem, but not one that’s related to Blynk.
It appears to be some issue with your ESP32 core add-in.
