I'm not really exactly sure why this is happening but it seems to be linked with #735 since it mentions the issue in the log

Totally my fault here, I set rust-version = "1.74" in my cargo.toml and tried to compile on my VPS. This lead me to find out my rust install was broken with two different installs causing version issues. Basically I had a rust version lower than 1.74.
