Adventurer 5m Pro - Issues with print quality

[the_link_keeper]

Hi everyoneI've been 3d printing for about two months now, and I've made some beginner mistakes but have generally been successful until recently. My prints suddenly all have the same issue, which is these weird issues with the layer lines, if someone could confirm what this is called for me I'd really appreciate it. I've purchased a filament dryer, tried PLA and PETG, tried going back to PLA. I've tried the built in benchy and basic cube on PLA to try to eliminate settings as the problem. I've also tried levelling the bed, swapping and cleaning nozzles, cleaning the bed itself.Is there any important hardware maintenance I should be trying? Sorry if I'm missing important information, but let me know if there is anything else I can provide.Thanks in advance for taking the time to help
