Failed Uploading exit status 2

Hardware help needed

So a couple weeks ago I was messing around witha a waveshare board the ESP32-S3-Touch-LCD-7 one. Then I put it off, and now whenever I try to upload something in arduino I get this message:

Sketch uses 1305427 bytes (41%) of program storage space. Maximum is 3145728 bytes.

Global variables use 96492 bytes (29%) of dynamic memory, leaving 231188 bytes for local variables. Maximum is 327680 bytes.

esptool v5.1.0

Serial port COM9:

Connecting......................................

A fatal error occurred: Failed to connect to ESP32-S3: No serial data received.

For troubleshooting steps visit: https://docs.espressif.com/projects/esptool/en/latest/troubleshooting.html

Failed uploading: uploading error: exit status 2

Last time I was using it it worked without any problems. So I don't know what is going on. TIA!
