Alright, then we have to figure out how this install is different.

1. How did you install the SDK?

2. How to you change between SDK version when you test for different versions?

3. Try to "build existing sample" instead of copying the sample. Does this behave the same?

4. Do you see similar issues with other samples?

We additionally checked other versions of SDK 2.8.0 and 2.9.0 and see the same problem. But it seems that the problem is purely local since it relates to a specific computer.
When downloading SDK version 2.8.0 and 2.9.0 (still downloaded via nRF Connect desktop) on other computers, examples with Matter is built out of the box without errors with `FLASH' overflowed.

It is not clear what to do with this, the error is clearly general, since it is reproduced identically on three versions of the SDK (2.5.0, 2.8.0, 2.9.0).

Steps (Nothing special):
1) Ceate a new application (Copy a sample);
2) Adding the build configuration for nRF52840dk, optimize for size with prj.conf (after attempt to build, I see that was include .overlay file too);

3) Try tot execute Pristine build or just build (the result is the same).

I mean: the steps you take.

A clean example of Light_switch (without modifications) with prj.conf:

Sorry I couldn't attach the error text to you (only a screenshot), I get an internal error about not being able to do this.

For prj_release.conf we have the same errors.

Our Matter samples in v2.5.0 should build out of the box. Let us try to find out why this does not work for you.

Can you describe what you do to build the lock sample?

Hi,
I have no impressions of your Matter samples, none of the examples for SDK 2.5.0 cannot be build.
That's why I opened this topic.
Please read the details of the problem above, if any other information is needed, please let me know.

Hi,

For comparison: How have your experiences with our out-of-the-box Matter samples been?
