unsolved I've been doing time tracking/licensure tracking this way since 2015... theres gotta be a better way. also, when will my excel file become corrupt?

TL;DR
I have 580 sheets, spanning since 2015. how much more can my poor little excel file handle? The file is about 3.5mb in size 😯.
So, i work in architecture, and this is generally how i track my time throughout the day. i will NEVER remember what i do when it comes time to doing my timesheets and this makes it way easier. i also have a place at the bottom that tracks my architectural licensure hours. i have to manually input that, and there are two sheets at the end that summarize this data (none of that is relevant i'm just including the explanation for context).
i've used this excel since 2015 and there is a "sheet" for every single week since about july of 2015.. so there are about 580 weeks/sheets... when will my excel explode and refuse to open? I've started saving a copy and backing up the file each week.
I'm open to a more robust system, but needs to generally have the UX (or similar) of this workflow. I have gone as far as vibe coding prototypes but i dont have the confidence that AI will be more stable than what i'm currently doing, and i'm not a coder so i can only take it so far.
anyway, input would be appreciated.
