Urgent Help Needed with LinkedIn Real Human Verification - Missing no CAPTCHA User Response Code

Hi everyone,
I'm an assistant for a foreign trade salesperson, and I'm currently using LinkedIn for customer development. However, I've encountered a problem during the LinkedIn real human verification process. It says that I'm missing the noCAPTCHA user response code or that the code is invalid.
I've tried clearing my browser's cache and cookies, updating my browser to the latest version, and using different browsers and devices, but the issue still persists. I've also checked my network connection and disabled any browser extensions that might interfere with the verification process, such as ad blockers and VPNs, but to no avail.
I've heard that some people have had success by switching to a different browser like Firefox and using a different proxy location, but that hasn't worked for me either. I'm really at a loss here, and this is hindering my ability to develop customers on LinkedIn.
Does anyone have any other solutions or suggestions for this issue? Any help would be greatly appreciated.
Thank you in advance!

Try using the forgot password feature and reset the password, they will send you a link and maybe you will be able to login from there
