Crash happened when adjusting operator props in Adjust Last Operation panel. When there are more than 32 objects selected in muti-object-editmode, we are running into RNA array limit (`objects_selection_count` is defined as an RNA array (which can only hold 32 entries, see `RNA_MAX_ARRAY_LENGTH`), leading to reading random memory errors. While there might be ways to make this work with more than 32 selected objects (e.g. by instead using a collection, or investigate supporting dynamic sized arrays for run-time RNA), this patch only cancels the operator with a report message (instead of crashing).
