I have recently started working on my school project which involves writing some c++ for the ESP32. At school everything works fine, but at home only the first time I compile and upload the project (using the Arduino IDE), does it actually work correctly. So the communication is there, it just seems that the first compilation step does something to the program, as every time after that first compilation it refuses to compile. Here are the console outputs of the two compilations:
First compilation (successful)

As you can tell, these error messages are not English, they are actually German. In the second compile step, they essentially say the following:
arduino-builder returned 2
Error during compilation of the Board ESP32 Dev Module
I am using Debian 12 (GNU/Linux) on my machine, but I don’t think that this would be the issue, as I am clearly able to upload the project the first time around.
Has someone here experienced something like this before? I have looked online, and most sources say that the error code was one and not two, so this seems like a different issue.
First thing first, check if this happen with a specific code, or with any code.
Create a simple Hello World project where you toggle a led or send a UART message and see if you have the same issue.
If you don’t have the issue with a fresh new project, then take a copy of your actual project, comment everything out of your main loop except a led toggle or uart message, and see if you have this issue. The goal here is to see if any library you use cause the issue outright.
At that point it should give you a good idea of where the issue is (board or code). If both things don’t trigger the error, re-add your code by sections and see if you can reproduce the issue.
If you re-add a block of code and the error triggers, then you know that something in that section causes the issue and you can investigate.
I can try to help.
The text / code thing isn’t working. Let me try.

As you can tell, these error messages are not English, they are actually German. In the second compile step, they essentially say the following:I can attempt to translate the German (either online or I can bug my wife lol)
Ok let’s see
category '' in the library ESP Insights is invalid and is set to uncategorizedI have no idea what that means. The translation is probably a bit off if the error uses tech jargon.
panic: runtime error: index out of range [7] with length 7Between the above and the go errors (wait, Arduino ide uses go??) it seems like something is messed up with the Arduino builder which I assume is the chunk of code that runs the tool chain to build? Maybe?
Are you on the same version of Arduino ide and board library as at school? Same os?
It mentions include cache. I wonder if there is something that isn’t cached initially permitting the build to work but breaks when the thing is cached on the second go round?
Or does it just fail every other time?
Idk this smells like something seriously jacked up in the ide or libraries. I don’t usually recommend it but it might be worth uninstalling, renaming your Arduino directory and nuking wherever Arduino keeps config files on your OS and reinstalling everything.
This is Version 2 IDE isn’t it? I haven’t messed with that at all. I tried and ran into some issue and decided to revert to 1.x until I have time to dive into 2.x head first.
PS: I do my coding on Linux also. The configs are in, I think, ~/.config/arduino (or similar) maybe also ~/Arduino for some libraries?
I think the version of the ide matching the one at school may matter a lot. Same for the esp board / library you’re using.
Arduino software: are you using snap or distro package or downloaded from arduino.cc or…?
