Got d1-mini clones and not able to flash them

perhaps interesting to share that I get the following in the IDE using WebSerial @115200. But gets stuck with Serial connected. Receiving data.... Flashed with DIO.

Disconnected.

And when on 115200 it just gives garbage and sometimes the /dev/tty.wchusbserialfd12240 disappears for a while. Sometimes till I unplug/plug again.
