Problem with lines where colon is used: invalid point

[RuzgarDogu]

There is a weird problem which might be related to my configuration, but

In lines where I use colons - such as if conditions or for loops - it gives the error "Flake8 error: invalid point" on the first line, instead of the line with the error.

Like the example given below, If I remove the colon in line 3, the linter highlights the first line where variable declaration is made, and says "Flake8 error: invalid point" while it should highlight line 3 with the actual error.

a = 1
for x in range(4):
    if x == 3
        print(x)

I tried with different versions of Flake8, uninstalled and reinstalled linter-flake8 but couldn't solve the issue.

Thank you in advance.
