Compile error that only happens when using sccache

[IceSentry]

I've used sccache in the past without any issues, but disabled it for a while. I recently updated it again and I keep getting errors that I don't get when sccache is disabled.

Here's the errors I get when building bevy:

I tried deleting the cache, stopping/restarting the server and even rebooting and I keep getting this error.

I'm on windows 10, sccache version is 0.8.1

I'm using sccache by adding this to my ~/.cargo/config.toml

[build]
rustc-wrapper = "C:/Users/Charles/.cargo/bin/sccache"

I've seen this exact error happen when there was a mismatch between the sccache version used in rustc-wrapper and the sccache server (0.3.3 server vs 0.8.0 client, specifically). Can you check if the server runs the C:/Users/Charles/.cargo/bin/sccache binary or if it's something else?
