Problem with starting advertising in Bluetooth

Question

Hello.
The problems with starting advertising started after I wanted to add NVS (most likely). The error occurs in the bt_le_adv_start function

What does this error mean and how can I fix it?

Here is my overlay for new memory partition (sensor_data_in_partition here for NVS):

/delete-node/ &slot0_partition;
/delete-node/ &slot1_partition;
/delete-node/ &storage_partition;

&flash0 {
	partitions {
		compatible = "fixed-partitions";
		#address-cells = <1>;
		#size-cells = <1>;

		boot_partition: partition@0 {
			label = "mcuboot";
			reg = <0x00000000 DT_SIZE_K(48)>;
		};

		slot0_partition: partition@c000 {
			label = "image-0";
			reg = <0x0000c000 DT_SIZE_K(204)>;
		};

		slot1_partition: partition@3f000 {
			label = "image-1";
			reg = <0x003f000 DT_SIZE_K(204)>;
		};

		storage_partition: partition@72000 {
			label = "storage";
			reg = <0x00072000 DT_SIZE_K(24)>;
		};

		sensor_data_in_partition: partition@78000 {
			label = "sensor_data";
			reg = <0x00078000 DT_SIZE_K(24)>;
		};
	};
};

Here is prj.conf

I use ncs 2.8.0 with the custom board with an nrf52832 chip.

I would be grateful for help.
