While waiting for more useful replies - note that your J-Link module version in the IAR IDE is 7.88j - quite old. Consider installing the latest J-Flash version from Segger. It should find and update J-Link module in your IAR installation.

Double check capacitance on VCAP pins, and measure voltage there. Check supplies generally.

Perhaps try with BOOT0 pulled HIGH

Hello @Luke_abc 

I am not sure if this is a similar thread [SOLVED] Unable to flash / erase STM32F401CC - J-Link/Flasher related - SEGGER - Forum

Same Error: Failed to restore target. RAMCode never stops
ERROR: Erase returned with error code -5.

It is related to bad board power delivery design.
