Looks like it's undercharged to me, or the txv is undersized. You said -32C evap inlet, and I see an uninsulated and sweating suction line where the bulb is attached, so that line is lower than dew point, higher than 0C. Superheat must be between 32C and 52C, in any case way too much!

If the txv is sized correctly for the load, add charge until you get a reasonable superheat in the range of 3C to 10C.
