I am not exactly sure how this can be reproduced, anyway I turned on my computer after I came home from school today and I everything was normal at first but then after launching certain apps like, Enigma, TPT Ultimata, Minecraft, etc... there was no titlebar on the windows and I couldn't resize any of them. Another thing was firefox and any other app I opened (except the ones without a titlebar) would open in fullscreen. I found this bug on a video on Plasma 5.4. I later found the fix when I saw a Plasma Mobile theme activated and I instaed switched it back to Breeze.

Oh yeah the video is this

STEPS TO REPRODUCE
1. Have computer shut down randomly I guess?? (I dont know I was at school when it shut off)
2.  have a plasma mobile layout as your desktop somehow

ADDITIONAL INFORMATION
Like I said I am confused on how this happened

This indicates that the system is misconfigured, and KWin fell back to the fallback window decoration theme, Plastik. I's recommend following up in a Debian-specific forum to learn how to safely customize the system. In the meantime, you should be able to switch to the default Breeze global theme to recover.
