B4R Question Error compiling Project

[Helmut S]

Hello community,

I installed B4R 4.00 on my Win11 laptop with Arduino IDE 2.2.1 and Arduino CLI 0.3.4.1. When I try to compile a previously well compiling project on the laptop, I get the following error:

cli: compile -b arduino:avr:mega C:\Projekte\Arduino\B4R\RFID_E~1\Objects\src\src.ino -v --board-options cpu=atmega2560
FQBN: arduino:avr:mega

Any idea what could be the reason?

Thanks in advance,

Helmut

In line 6 it says error.
Searching on Google for recipe.preproc.macros showed this as first hit.
