Hi,
I was able to reproduce the issue again, thanks for sharing the video. I will debug this issue tomorrow with the person who has implemented it and will update you accordingly. Thanks for your patience.

Hi Hexasense,
Upon investigating further, the reason for the crash is figured out. The operator <> is not supported in our filters yet. Please see the supported valid operators here: https://bryntum.com/products/grid/docs/api/Core/util/CollectionFilter#typedef-CollectionCompareOperator. You will have to use != instead of <> because we do not support the creation of new operators. operators config is only the subset of the valid operator values.
You could also try using the filterable config on a column to define your own filter function and handle your non-standard operators there: https://www.bryntum.com/products/gantt/docs/api/Grid/column/Column#config-filterable. The code snippet in this docs link showing filterFn is what you'd need to try.
