Sequence at power on, Prius V not going to ready only shifts to neutral

Update:
------------

Finally got it working, after we fixed inverter connection, we tried boosting up again. Funny thing is that when the battery is very low, the battery has a lot of current draw. In my mind there must a a relay that's powering up a motor somewhere, not a safe design in my opinion. Didn't had time to find out where it's coming from. It got me very worried at some point thinking there's a short somewhere.

I don't think it's a problem with my car since at 11-12V, the whining sound coming from the engine bay disappears. I observed it last night after parking and with the 12V battery charged, and again this morning and it is quiet. Could it be also the hybrid battery powering up one of the motors? Questions, questions... Could the 12v relay that powers up the interlock on the hybrid battery gets stuck at a very low 12v battery?

I took it for a drive with the dash lit like Christmas tree, since my scanner showed no issues with the Hybrid system, after the inverter connection fix.

The crankshaft and camshaft P0335 and P0343, the mass airflow sensor low and air intake temp high, P0102, P0113 stayed on until I drove for about 5mins.

An error B2313, electric window, passenger door, I was able to clear this morning following the procedure in one of the posts here, which was to do some form of calibration for the drive motor, i. e. hold the passenger side button for a couple of seconds after it reaches the ends.

The last lingering error about the speed sensor on the wheel hub but i forgot the code, I'll pull it out again at some point and post it here.

Was just relieved the transmission is good, as that was the bulk of the work and I couldn't imagine if it was bad that we have to do the work all over again or scrap the car

Thanks for the responses, it certainly helps to get information here when one gets stuck with issues.

 

These are the pictures of my transmission and clutch/damper disk before we changed them. Both are broken.

 

How can I upload images now? I tried upload a file button and it went through but where does it go huh?

 

Second try, used to be easier before to upload images...

Springs been broken since 2018 making rattling sound when driven (daily)

It finally gave up tho not too quickly

I suppose the motors MG1 an MG2 still good? Never opened the assembly to find out

 

I'm using my phone but it's working now
