There is a problem with my NDK environment

yzbruh@thin-15-b12ucx:~/Development/android-ndk-r28b$ ./ndk-build
clang: error: no input files
/home/yzbruh/Development/android-ndk-r28b/toolchains/llvm/prebuilt/linux-x86_64/python3/bin/python3: line 1: python3.11: not found
[arm64-v8a] Compile++      : helper <= Checkers.cpp
clang: error: no input files
make: *** [/home/yzbruh/Development/android-ndk-r28b/build/core/build-binary.mk:423: /home/yzbruh/srclib/libhelper/obj/local/arm64-v8a/objs/helper/Checkers.o] Error 1

The log is clear, python3.11 is already present in the same directory but cannot be called directly. And the existing files are not processed/exported properly... I couldn't find a solution to the problem.
The NDK_PROJECT_PATH variable is set correctly.

I'm using Fedora 42 and of course bash. There was no such problem in Ubuntu...

For more details, here are the contents of Android.mk and Application.mk..:

jni/Android.mk (source files are of course in jni):

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := libhelper
LOCAL_SRC_FILES := \
	Checkers.cpp \
	Classes.cpp \
	FileUtils.cpp \
	Sha256.cpp \
	Utilities.cpp
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../include
LOCAL_CFLAGS := \
	-Wall \
	-DLIB_BUILD_MODE

include $(BUILD_SHARED_LIBRARY)

jni/Application.mk:

APP_ABI := arm64-v8a
APP_PLATFORM := android-21
APP_STL := c++_static

./ndk-build

You should not be building from within the NDK's install directory. It's no longer possible to reason about the behavior of the NDK after you've written to the install directory. Uninstall and reinstall your NDK, then move your source to a separate directory, and run ndk-build from that directory, not from the install directory.
