I cannot upload sketches to my board with the desktop apk or Arduino IDE after I tried to update with a new version of OpenCat. I get a continuos yellow led and no beeps. Dr.Li in the Github issue advised that the bootloder might be broken and needed to be reset. I have gone trough the documentation for Arduino Ias ISP. I can't figure out how to connect the jumper wires. do I connect it with the USB serial adapter. The pins GND, RTS, 5V RX, TX, and DTR on the adapter connect to which pins on the Arduino? Will it be easier to use a USB ASP AVR Programming Device for ATMEL Processors (see attached picture), if so how to connect it? Will resetting the bootloader solve the issue? or is it hardware related?

Arduino gives the following error Arduino: 1.8.19 (Windows 10), Board: "Arduino Uno"

Sketch uses 30006 bytes (93%) of program storage space. Maximum is 32256 bytes.

Global variables use 1766 bytes (86%) of dynamic memory, leaving 282 bytes for local variables. Maximum is 2048 bytes.

Low memory available, stability problems may occur.
