Sorry but it still fails with this error:
https://pastebin.com/6Y4HTNfF

I've used the SHA1 you've pointed me that I've seen that refers to:
2022.02.12

I've used buildroot/utils/docker-run too and the error is the same.

Can you please take a look at it?

Maybe it would be better using at least version 2023.04 otherwise even
if it builds and works on the board we're not sure it works on master
branch.
By the way on master branch the error is the same and it's due to libepoxy.

Thank you!
