Twitter Account Lockout - Unable to Access Due to Old Phone Number

I'm having trouble accessing my Twitter account because my password is linked to my old phone number and I can't remember it. Instead of sending the verification code to the email address I didn't save, it's being sent to my old number, which is causing me difficulty in logging in. I am currently able to access my account on my phone, but I encountered an issue when I deleted my number. When I attempted to add a new number, it prompted me to enter the password, which was associated with the deleted number. I am unable to access the app from any other location, and due to some apps being connected to Twitter, I am also unable to log into them. This has been my sole account used for years. I sent an email, but unfortunately, I didn't receive a response. I'm relying on your assistance.
