UV A/C Dye contamination

Hello i recently purchased a 2015 ct200 that had been in a fender bender and replaced the condenser, i rented a vacuum and guage set from autozone and attempted to fill the Freon. After about 15 minutes of slow filling I got the compressor to kick on and the high side started filling up faster to 95 which it then stopped filling, the low side pressure keep fluctuating down to 20 when I close the valve for the r134a can, but fills back up to 90 for a about 7 seconds when I open the valve, the low side is consistently fluctuating back and forth but the high pressure seems to be stuck at 95-100 range and I can not possibly get it to go higher than that after 2 hours of attempted filling. Compressor was engaged and running constantly. Low pressure line felt ice cold to the touch a couple times I checked but was not staying cold. A/C still blowing warm. After I took off the Low pressure coupler I noticed the Low pressure port is covered in U/V Dye, after reading online I have heard that this can cause compressor failure and needs a full flush and compressor, condenser, and drier replacement, I also read somewhere else that it just needs to be evacuated with vacuum again and filled this time with non contaminated. I am not sure what my next steps should be as there is not much discussion online of this topic. I am unsure if the A/C was operational before the crash but I believe it was. Any and all advice will be appreciated thank you.
