El software de Adobe es peor año tras año

Hello thanks for reaching me out, there are several bugs, for example, im working with black C 0 M 0 Y 0 K 100%, after finishing my design all letters changed to a weird black with random C M Y K % when I did not change them, had to manually set them up again, some of them did not let me change the color, tried to manually put the numbers, didnt work, tried to use the eyedropper tool, didnt work either, had to save, close, restart, didnt work, had to reinstall software to be able to put the right color, all texts changed suddenly and ruined my design and time. there is another bug where the vector made shapes nodes seem to be in a specific place but it turns out that it moves, it looks like when you have a shape and select and image and press ctrl + 7 to create a mask, and the edges of the image are not aligned with the shape, exactly like that, and moving the shape and putting it into the right place is so fraking annoying, im working on a packaging project and i need accuracy, something illustrator has stopped giving me a couple month ago. There are some other bugs like an object appearing as selected no matter what you do, it's impossible to unselect it, this creates confussion, the only way to resolve it is to close software and restart PC... this happens at least twice a day.
