Is something wrong with me..

I’ve been trying to get into dating here recently. I’m 23f and on all the apps. Every time I match with someone and we get to talking I’m ghosted 2 days later or I’m told “I don’t put in any effort worth continuing this conversation”. I just don’t understand I message fast and try to keep a conversation going but it’s never enough it seems. This has happened enough that I’m realizing I’m the problem I guess. I am a very shy person in general and do have trouble having conversations with people but I’m trying my best to not be dry or seem un interested. It usually takes me a couple weeks to become at least a little comfortable with someone so I can have a more natural conversation with them but no one ever sticks around that long. I am an introvert and my friend is an extrovert. She says I’m just not talking enough and engaging with the people I match with to want to stay. I promise I am but maybe I ain’t. I sometimes have absolutely no clue what to say to people. Like my brain goes blank and I’m stuck. Which puts a lot on the other person to continue the convo I am aware. I feel like I’m fighting with my brain to think and stay in a conversation with someone. I want a connection with someone and to be with them but idk why my brain can’t help once I’ve got someone’s attention. Once I can warm up to a person I’m a lot better but I can’t seem to get past my awkward stage of not knowing what to say before they get tired of me and end the conversation. I’m just wondering what’s wrong with me because I try my best and nothing ever works. Any advice would help really. Maybe I’m just not hardwired to be able to connect with someone but that’s all I really want. To have a deep connection with a person to spend my life with. Maybe I won’t ever have that though. Sorry my mind runs off sometimes but if anyone has advice it would be appreciated.
