Stuck at Bootstrap system/Loading items

Since around the start of this year i’m unable to launch rust. Whenever i try launch it, it stops at either “Bootstrap system” or, “Loading items”. This does not happen when launching through RustClient in rust’s folder, but since EAC doesn’t start, i can’t really play anyway.

What i’ve tried so far:
Re-install Rust
Re-Install EAC
Validate game cache
Run in Win-7 compatibility mode

Rust is installed on an external 3.0 USB HDD (works for all other games), PC specs are above the recommended and i’m running on Windows 10.
