Exec format error on Fedora 36 (kernel: 5.19.16-200.fc36.x86_64)

[jackrendor]

Hi. I have some issue regarding the install of the kernel module.
I made sure to switch branch (to workstation-16.2.4 which matches the current vmware installation) in order to have everything I needed to compile and install the modules.

But when I run the following commands:
modprobe -v vmmon; modprobe -v vmnet

I get the following:

modprobe: ERROR: could not insert 'vmmon': Exec format error
modprobe: ERROR: could not insert 'vmnet': Exec format error

So what am I missing out?

Not sure if this might help but my gcc version is: gcc version 12.2.1 20220819 (Red Hat 12.2.1-2) (GCC)
I followed the info in the INSTALL files (so changing branch, compiling with make, installing with make install and also signed up the files for my secure boot) yet I still have this error.

IIRC some people got this error when they had "secure boot" enabled and forgot to sign the modules. Could that the the case here?

My secure boot is enabled, yes.
Also created the certificate and signed up the files with the following script:

for modfile in $(modinfo -n vmmon vmnet); do
  echo "Signing $modfile"
  /usr/src/kernels/$(uname -r)/scripts/sign-file sha256 \
                                /misc/sign-vmware-modules/MOK.priv \
                                /misc/sign-vmware-modules/MOK.der "$modfile"
done

I also "added" the cert to my "secure boot" by importing it with mokutil --import MOK.der
And after rebooting I also followed the configuration in the secure boot to properly apply the cert.

Even tho I thought secure boot was the problem, I tried to disable it and tried to run the previous modprobe commands, ending up with the same results.

Any other clue or logs that I can post here to help?

Thank you a lot for answering tho!
