Short answer: No. There is always a risk of possible errors or malfunctions.
Extended answer: Keeping our umbrelOS always up to date. The instability and constant errors in each update have led many umbrelOS users to adopt a terrible practice: not updating for fear that everything will stop working correctly. If we add to that the user who believes that the issue is to install umbrelOS, the apps that I need and forget about everything… Well, we have a magnet for problems.
Updates are necessary because, apart from aesthetic changes, they contain solutions to previous problems, performance improvements, new functions, etc.
umbrelOS is based on Debian and, with each update, you not only update umbrel, but also Debian with its own system updates. The apps that you have installed in umbrel are also updating.
In short, if you do not keep your version of umbrelOS up to date, you put yourself at risk and will get into trouble in the medium term. The worst thing is that you don’t get rid of the problem, but rather, most likely, when it explodes in your face it will be worse and require more time, work and effort to solve it.
