Under normal circumstances, the connection prompt is

connecting....._____....._____

This may take a long time, but at least the connection will be successful.

When the flash is erased and the power is accidentally cut off, the connection will be stuck in "connecting...".

esploader.js
 async connect(mode = "default_reset", attempts = 7, detecting = false) {
        let i;
        let resp;
        this.info("Connecting...", false);
        await this.transport.connect(this.romBaudrate, this.serialOptions);
        for (i = 0; i < attempts; i++) {
            resp = await this._connectAttempt(mode, false);
            if (resp === "success") {
                break;
            }
            resp = await this._connectAttempt(mode, true);
            if (resp === "success") {
                break;
            }
        }

I speculate that the program is stuck at 'await this.transport.connect(this.romBaudrate, this.serialOptions);',but I don't know how to solve it.
I tried to flash the firmware using esptool.exe, and esptool.exe worked normally. So the device itself should be fine.

Which board or chip are you using ?

Could you copy the trace ? Which Baud rate are you using ?

Chip is ESP32-D0WD-V3 (revision v3.0)
Baudrate is 115200
trace keeps printing a lot of the same stuff, filling up my console
