2010 xc90 reduced engine performance

[Windmu20]

Hello, my 2010 Volvo XC90 3.2 is not starting. To give a little back story…. My compressor clutch was broken and eventually broke the serpentine belt. I replaced with new compressor, belt, tensioner, and pulley. It ran great. I brought it to mechanic to evacuate and charge the ac system. He charged system and went to turn on compressor but fuse was blown. Apparently common for failing clutch. When he inserted new fuse the compressor engaged. It ran for a a sec then car died. Now car will not start. It turns over and sometimes fires up for a second then dies. It says reduced engine power. It has seven codes that cannot be cleared. 4 are throttle position sensor, 1 ac refrigerant pressure, 1 barometric pressure sensor, and one other see attached. All seem unrelated. Tried starting with fuse out. Checked all wiring for install and ecm harness pins all appears good. He said the moment compressor engaged everything went from there. Accelerator will not engage when depressed. Battery is good. Please help

Codes
