I also have this issue, but I have to say that there honestly is no solution, and I have a guess as to why.

You see, the pandemic froze all of the manufacturing of new cable boxes.  All of the boxes are refurbished, which means that the procedure to get you a working cable box only making sure that the cable boxes that run these apps have the ability to get into the app.  There is no stress-testing, and even if that were done, there would be no point in doing so.

These boxes have tremendously poor onboard memory.  I am talking about RAM.  RAM speeds are atrocious, and the actual only benefit is that at least the RAM works, and is probably replaced on refurbished devices.  However, it remains a bottleneck.

So, here's my guess: The developers of the apps that are allowed to code for X1 support have to make do with the poorly written technical specifications that they are given by Xfinity Corporate.  Let's suppose we compared the development process with video game developers working on console ports.  There is a lot of information about those specs because the industry of the console is made to work with developers.  Xfinity, however, is not.

Why would they?  They have what they consider proprietary hardware, but essentially it's all refurbished hardware.  The hardware may boast X1 App support, but the sheer amount of boxes they have to ship out makes it logistically difficult to make these boxes carry the adequate specs needed to run these apps, especially when the monthly cost of these boxes are only a portion of the entire service plan which includes giving you access to cable and internet.  (You can't use X1 apps without both cable and internet.)

Anyway, the app may have been built by these developers, but, your box runs out of memory before it can even function correctly.  This error is a memory one.  Perhaps we could surmise that some of these functions within the app runs more memory than is available, due to the poor speeds.

Personally, I would want to know if these errors are being generated by the app via some sort of Xfinity API, or if it is bound to the firmware of the box.  Perhaps there are some hard limits set that force the ideal technical specifications to become lower than the hardware limits.  I'm talking about max temperature limits, OS/firmware overhead being increased, things like that.

Whatever the case may be, customer support is going to be unable to assist.  What they really need to do is create bug tickets on the X1 App, delivered by Corporate to the developers.  I also think that these developers need to get more testers in the team; being able to run some basic performance tests on each function of theor app.  If they had that, their tests could indicate the problem functions and reduce their overhead.
