insmod: ERROR: could not insert module xline.ko: Invalid module format

I am trying to build a driver for a Heber X10i I/O controller on my Fedora 34 but I fail to insert the module into kernel, says "Invalid module format".

I followed all available tutorials/hints/Q&As but still no luck getting this running, am I experiencing some bug on Fedora side? Any perspective idea would be more than welcome.

Makefile:

xline-objs := xline_driver.o
obj-m := xline.o

KVERSION:=$(shell uname -r)
KDIR:= /lib/modules/$(KVERSION)/build
PWD:= $(shell pwd)

modules:
    $(MAKE) -C $(KDIR) M=$(PWD) modules

install: modules
    $(MAKE) -C $(KDIR) M=$(PWD) modules_install
    depmod -a

clean:
    $(MAKE) -C $(KDIR) M=$(PWD) clean

all: install

The compilation goes fine, result xline.ko is present and it's modinfo is as follows:

I tried to find kernel-headers 5.13.12 but no success.

One remark: the driver code xline_driver.c was outdated, so I fixed it - but that should be an executable problem (if any).

EDIT: whole procedure with the code works on linux-mint (ubuntu) 5.4.0-74-generic (why not on fedora?)
