SyntaxError: invalid syntax

The python version is wrong.
I tried to remove all python versions (2.7 and 3.5) and manually installed python3.9.
but the error still remains.

Sorry, but I don't understand your issue. You didn't provide enough information and you did not follow the Issue Template.

We have no idea how you installed GEF and what version you're using (latest is not very specific and more often then not people are not actually using the "latest" version).

Also provide us with as much information as possible about the specific error you're encountering, including all displayed error messages.

When you say something like "wrong python version": Are you sure that you're using GDB with python-support?

any updates on this issue?
reproduced on my side, following the installation steps:
https://github.com/hugsy/gef#instant-setup
either curl or wget and then execute gdb will give that error.

[ans1genie]

anyway to restore the gdb to it's working state.
open the .gdbinit file and remove the line for sourcing the gef python script.
for my case, I removed that line :

$ cat .gdbinit
source ~/.gef-2b72f5d0d9f0f218a91cd1ca5148e45923b950d5.py 

[hugsy]

The python version you have compiled with gdb is too old, doesn't support f-string. Run

$ gdb -nx -ex 'pi sys.version' -ex quit

And post the result here.

@hugsy result :

[hugsy]

As I suspected, your version is too old for both Python (3.5.2) and GDB (7). Install or compile a newer version. See https://hugsy.github.io/gef/install/

thanks for the help @hugsy
