Error failing to download file??

Hello....

I am using STM32CubeIDE 1.10.0. I purchased a LoRa-E5 from Seeed. The E5 has proprietary code on it that one must use a UART to talk to the device. I would like to basically erase the device and load my own code onto the device. I have created a very basic project in CubeIDE for the STM32WLE5JC which is the processor on the E5. At the moment my code does nothing more than toggle PA3 high and low. When I try to load the code onto the DUT I get the following error on the console:

Erasing memory corresponding to segment 0:

Erasing internal memory sectors [0 3]

Download in Progress:

Error: failed to download Segment[0]

Error: failed to download the File

Further reading seems to imply that the RPD bits are somehow set and I need to set them to Level 0. Can someone please confirm that yes this is actually the problem? And how using CubeIDE I go about doing this?

I am very unfamiliar with this environment and would prefer to use CubeIDE rather than command line, etc. I was under the impression that CubeIDE contained all the underlying tools (ie Flashing Tool, CLI, etc) so it seems logical it could be done using this.

thank you

UPDATE

after watching a youtube video I decided to give the STM32CubeProgrammer a try....By default it wanted to load onto my C drive which is full so I chose the D:/Application/ST/ drive which has in it STM32CubeIDE 1.10.0....During install it said it may write over things but I accepted anyway as I didn't think it would affect CubeMX. I was able to change the level back to 0 on the part BUT now CubeIDE/MX will not allow me to connect anymore to the STLINK-V3SET ...I get the following:

Can someone please tell me if I can get back to using the IDE somehow without uninstalling and re-installing???
