Funny enough, I had the exact issue the OP had with my M1 iPad and Notes, writing down Kubernetes coursework and notes by hand to try and make it "stick" better mentally (an entirely different post, someday) only for Notes to crash, losing most of my work since the last time I opened the app. It got so bad that I was regularly synchronizing and duplicating notes to preserve my work ahead of the next crash, and splitting notes up into quarter-chapters to reduce the likelihood of app crashes and iPad overheating.
Apple has been so feature-focused to keep up with shareholder demands and industry fads, that they've neglected the core user experience. iTunes used to be the best way to organize and consume music, and nobody has really taken up that mantle since Apple abandoned it in favor of their streaming service. Same with local media and shared libraries, now tucked away into obscure apps in favor of more streaming platform priority.
That feature-focus extends to general OS stability as well. Safari gulping down battery life on my iPhone because it's not properly suspending tabs anymore. iPad suddenly no longer charging without any error message or warning until a reboot is triggered or the battery completely dies. Siri responding as far away as physically possible from the actual speaker, including on devices I don't even own, bypassing multiple other devices that stand between the speaker and the responding device. The AppleTV needs weekly reboots because apps don't load video streams properly, giving a black screen with audio or an HDCP error message despite every other device in the chain showing it's the AppleTV not engaging HDCP. HomePods suddenly ceasing music playback without any command to do so, often mid-song.
It's just getting worse and worse, to the point (pre-RIF) I was seriously looking into an honest-to-god HiFi to replace stereo homepods in my bedroom. I've already ditched the Music app in favor of Plex's Music App (don't even get me started on how awful it is, but it's still better than Apple Music), I've all but given up engaging in music discovery via CarPlay, and I've long since moved local media onto a Plex Server in lieu of a single, simple, efficient iTunes library. That's just the media side of things, too.
Don't get me wrong, Apple's kit is still lightyears better than an equivalent Windows 11/Android setup, especially for my family members who don't want to wrangle with confusing UX and have largely moved into a streaming-only lifestyle - though even they're increasingly frustrated with Apple's updates breaking things or forcing them to rework their processes.
But that only works for so long before users get so sick and tired of it, that they'll take a chance on an upstart competitor.
