[tpm2] Error: "Could not initialize TCTI file" when calling tpm2_nvreadpublic

Hi, 

I am using the tpm2 tools combination below:
tpm2-tss-2.3.2-fb1.x86_64
tpm2-abrmd-2.3.1-fb1.x86_64
tpm2-tools-4.1.1-fb1.x86_64

After initial installation, I got an error when running tpm2_nvreadpublic. (installation sequence tss -> abrmd -> tools)
Could anyone please let me know how I can resolve this issue? thank you so much in advance.

~$ tpm2_nvreadpublic

if I do a restart "service tpm2-abrmd restart", then this issue can be resolved. I would like to resolve this without using the workaround.
