Anyone migrate to OS 10 and find new bugs pop up in their game?

I recently migrated all my apps from OS 7 to a new computer running OS 10 and a few new bugs popped up in my Unity game file. It has been months since I last worked on my game and when I picked it up again on a new computer/OS some things weren't behaving like I remembered they did when I last tested it. Bugs I could not locate in any of the scripts and I am usually quite good at tracking down bugs. After trying everything - on a whim- I opened the file on my old computer and the problems were not there. Could it be that the new computer is so much faster that coroutines start time needs to be altered? That is how I fixed one bug on the new computer version of the file, by starting the coroutine .1f later. The old computer a mechancal hard drive os 7, the new one a SSD running windows 10. Though it worked for that bug I don't think it makes sense and doesn't explain the other bugs that popped up
