Your issues are not normal. For example, here on my Studio, the uptime is 9 days, with Sublime Text started from the beginning and used quite heavily during most days. It has 5 windows with 5 to 10 tabs in each with no issue whatsoever. My experience with my previous (Intel) Macs was about the same; I haven't seen visible effects of the ISA change besides not hearing any fan anymore (and a speed bump, but I tend to use my computers for a very long time, so there is always a speed boost when I get a new one).
If it is under warranty, it's probably worth having a chat with Apple support. Otherwise, I would recommend trying to diagnose hardware failures (particularly RAM; beyond 8GB it should not swap regularly-used applications).
MacOS is rightly criticised for becoming less robust in several ways, but that is mostly fancy new features. And Time Machine. For some reason they cannot seem to get it perfect, which is a shame because it is the best backup solution I have used yet. The core OS is quite reliable and really should not crash things like that.
[edit] There is a wealth of information about AS Macs here, the site is well worth a bookmark: https://eclecticlight.co/mac-troubleshooting-summary/
On qBittorrent specifically the application can often "feel" like it is hanging because it brings up modal windows behind the main window, meaning you need to drag the main window away to interact with the modal and the main window will be unresponsive in that time. This may make it feel like it is hanging, when really it's just down to a non-native macOS application not using the correct APIs to display modal sheets
I do occasionally get other application crashes, maybe a couple per month, usually it's down to the application doing something it shouldn't. My current macOS uptime is 28 days, which is when I last installed an update that required a restart
To be fair, MacOS itself doesn't seem to have issues. There seems to be no upper limit to possible uptime. It's just applications.
But without knowing the machine and OS version that you have my data point is perhaps not very helpful.
I would definitely take it in to be looked at. That should not be happening. Crash logs will hopefully point a finger at the problem.
Have you tried reinstalling everything from scratch? If yes, then it is very likely a HW issue. If others suggest a better method for checking where the fault lies, other than reinstalling, then follow their advice.
