Instaloader fails to download all private profiles and downloads all public ones anonymously.

Bug Description Preface: I am not blocked from the tested Instagram accounts and can access them while logged in on a web browser. I’ve also tested this on multiple computers from multiple IP addresses. It’s present on MacOS and the prepackaged executable on Windows. Version 4.2.10

I enter the command: instaloader profileToDownload --login=myUsername. Each time I attempt this, instaloader says the profile has changed its name. The changed name is the same as the original one. Then it states that the profile doesn’t exist. Next, it tries to download anonymously, which fails because the profile is private. It gives the error that login=USERNAME is required, even though I logged in already. An example output is below:

instaloader testProfile --login=myUsername
Loaded session from PATH\session-myUsername
Logged in as myUsername
Trying to find profile testProfile using its unique ID 11111111111.
Profile testProfile has changed its name to testProfile.
Profile testProfile does not exist.
Trying again anonymously, helps in case you are just blocked.
Warning: testProfile will be downloaded anonymously ("Profile testProfile does not exist.").
Downloading anonymously: testProfile
testProfile/2019-04-28_06-07-45_UTC_profile_pic.jpg already exists
testProfile: --login=USERNAME required.
Saved session to PATH

Errors occured:
Warning: testProfile will be downloaded anonymously ("Profile testProfile does not exist.").
testProfile: --login=USERNAME required.

A similar situation happens with public profiles, although the requested files are downloaded. In this case, I get the following output:

instaloader testProfile --login=myUsername
Loaded session from PATH\session-myUsername.
Logged in as myUsername.
Trying to find profile testProfile using its unique ID 11111111111.
Profile testProfile has changed its name to testProfile.
Profile testProfile does not exist.

To Reproduce Steps to reproduce the behavior: instaloader profile --login=myProfile

Instaloader version 4.2.10

Additional context Again, I’m not blocked from the profiles I’ve been testing. This happens with every public and private profile. Either it’s private and not downloaded or public and downloaded anonymously.
