Debug console gets stuck

Debug Console:

[2022-03-16T23:39:05.855Z DEBUG codelldb::dap_codec] --> {"command":"evaluate","arguments":{"expression":"p *d","frameId":1006,"context":"repl"},"type":"request","seq":61}

    *d
    ^~

As we can see in above captures, p d worked once, then it took 14 minutes for response of p *d . This huge delay is not specific to any particular variable/expression. sometimes it works instantly and then next time it gets stuck
