This seems to be related to version 3.2 of esptool which is included.
These are the two related tickets on their tool:
espressif/esptool#721
espressif/esptool#685

esptool v3.3-dev seems to be fixed.

Downgrading to nanoff 2.0.15 which was the last release before esptool was upgraded to 3.2 also works.

2.0.15 output:

 dotnet tool install -g nanoff --version 2.0.15
You can invoke the tool using the following command: nanoff

@tomglover24 thanks for pointing out that there's a new release of esptool. We'll update the one in nanoff and let's see if this fixes it.
