Query - view with sum/truncate/floor() erroring: rowgroup.h@821: assertion '0' failed

We run mariadb 10.6.16 with cs plugin 6.4.7 and we get error on a query over view:

The same issue is observed with all other functions - ROUND, TRUNCATE, CEIL, FLOOR.
If we remove them everything is OK.

No such issue in version 5.6.2.
