core: ValueError: Timeout value out of range - python3.12 issue - downgrade to 2024.2.4 fixes the issue

The problem

After updating to 2024.2.5 there are various python errors with the modbus intergration

My automation is sending modbus write registers to 2 solar inverters and both are failing after 2024.2.5

I can confirm after downgrading to 2024.2.4 the automations now work

What version of Home Assistant Core has the issue?

2024.2.5

What was the last working version of Home Assistant Core?

2024.2.4

What type of installation are you running?

Home Assistant OS

Integration causing the issue

Modbus
