Unable to Access TikTok Lite on Android Due to Regional Restriction Error

Hello, I haven’t been able to access my TikTok account for four days. Every time I try to log in, I get the message, "Our services are not available in your country or region." This issue came out of nowhere, and I have no idea how to fix it. I’m using an Android device with TikTok Lite, and I need help resolving this problem so I can access my account again. Can someone from TikTok please respond to me? I need to know how to bypass this issue and regain access to my account as soon as possible. Any assistance would be greatly appreciated!
