Hello I got an ESP32-WROOM-32D from aliexpress but when I try to upload the 'bare minimum' code I get this error:
WARNING: Failed to communicate with the flash chip, read/write operations will fail. Try checking the chip connections or removing any other hardware connected to IOs.

It uses the CP2102 for which I have the driver installed already. How can I fix this problem?
if you run the Device Manager does COM port appear/disappear as plug/unplug the microcontroller?
if not do you get any message, e.g. "USB device not recognized"
disconnect everything (sensors/relays etc) from the board
try a different USB port
try a different USB cable (some are charge only)
try different EN / BOOT/ RST button combinations
in the Arduino IDE select File>Preferences and enable "Verbose output during Compiling and upload" then attempt to compile and upload your program again
if there are still problems upload the error messages as text
Thank you for your reply. I checked the cable with another esp32 and the cable seems to be fine. However the odd thing is, when I connected another esp32 the port showed up different on arduino ide despite the cable being connected to the same usb port.
I still get this error:

what does you Tools>Board look like, e.g. mine is
if the USB cables are OK it looks like you have a faulty board (I have had a USB socket on the ESP32 come loose - had to solder it back in place)
do you have anything connected to the board? e.g. sensors, relays, etc
does a simple program, e.g. blink, give the same problem?
Thank you for you reply! Currently I am only trying to upload 'Bareminimum' and I get this error:
I have attached the image of the Tools section as well.
