Encountered an error when compiling the s3b.yaml file from the main branch.

[Schr0dingerCat]

Sorry for my poor English.
My OS is Ubuntu 25.04, which comes with Python3 pre-installed.
I then ran:
git clone https://github.com/BigBobbas/ESP32-S3-Box3-Custom-ESPHome.git
Following the ESPHome official installation guide, I created a directory in the project folder:
mkdir .box-venv
Then:
python3 -m venv .box-venv
Activated the virtual environment:
source .box-venv/bin/activate
Installed ESPHome:
pip3 install esphome
esphome version: 2025.7.5
All previous steps completed without errors.
However, when executing:
esphome compile s3b.yaml
The following error occurred:

INFO ESPHome 2025.7.5
INFO Reading configuration s3b.yaml...
INFO Detected timezone 'Asia/Shanghai'
INFO Generating C++ source...

I’ve Googled the error but couldn’t find a solution.
