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
