Opening an application to visualize charts through the hub, the visualization may fail and the error "Out of calculation memory" will be printed.
The issue is often related to having an app that is too large or requires a re-design or general optimization. A poorly designed application can lead to memory leaks.
Review the application and optimize as needed to prevent performance problems for the engine service.
Verify that the servers hosting the Qlik Sense engine service have sufficient resources (CPU / Memory) to proceed with the calculation. It is highly recommended to have at least 16 cores and 64 GB of memory.
You can otherwise change the timeout.
The "Hypercube memory limits" limits how much memory a hypercube evaluation can allocate during a request. If multiple hypercubes are calculated during the request, the limit is applied to each hypercube calculation separately.
If it sets to 0, the engine applies a global heuristic which basically ensures that it doesn't run more than 1 "big" calculation in parallel.
If you set this value to -1 then you will disable the limit and allow the Engine to keep trying to load the application.
The negative value disables the limit, but it wouldn't exceed the limit set under the Max memory usage (%) or Memory usage mode.
Qlik Sense: "Calculation timed out" while loading a chart into an application
This is a very clear explanation. Thanks a lot!

This solved my similar issue, thank you.
