Did my laser die?

[Xignals]

I have a LG WH14NS40 MT1959 drive I bought back in 2018. It has been lightly used over the years but recently I have been ripping mostly DVDs and about 5 Bluray discs. I have a few UHD movies and found that this could be flashed to read those. I successfully flashed to WH16NS60 and popped in a UHD movie. It saw and read the disc. However when it went to rip the movie it started making some really strange sounds then CRC errors started happening and it aborted the rip. Pulled the disc and closed the drive to let it reset. Then tried again. This time I got the same strange reading sounds then some errors about a certificate being revoked and then NO Disc. At this point it quit reading anything but a audio CD which it was able to play and showed all the tracks. But no other type of disc would read, data, DVD, Bluray. I gave up for the night and turned the computer off. Came back the next morning and forgot I had left a DVD in the drive. It saw the disc and played! I started to rip the movie and it was running at only 1.1x and close to the end it started throwing CRC errors and eventually just errored out. After that it quit reading anything again except for audio cds.

The drive still shows up in Windows and shows all information in MakeMKV however when a disc is put in it does try to read for about 10 seconds but never sees the disc. Did the laser burn out trying to read UHD discs or was it just "its time to die"? It had been working great up until that UHD disc. That disc was brand new and had only been played once.

Thank you.

You can try cleaning the lasers

But also always let the os see the disc first before Opening makemkv do it the other way causes issues
