I Can’t Log Into My Instagram Account Even Though My Username and Password Are Correct

I am incredibly frustrated with Instagram right now. Every time I try to log into my existing account through the "Log In" section, I carefully enter my correct username and password — but no matter what I do, the app refuses to let me in. Instead of accessing my account, I keep getting an error message saying, "Sorry, we couldn't complete your request."

I have double-checked my information multiple times, cleared my app cache, updated Instagram to the latest version, and even tried logging in from different devices — yet the problem still persists. This clearly isn’t a user mistake; it’s a technical issue that Instagram needs to fix immediately.

I urgently request Instagram Support to step in and resolve this login problem. I should not be locked out of my account when I'm providing the right credentials. Please fix this issue without further delay — I just want to access my account again!
