When I run the below code, I get the error "Error using table2array (line 34)
Input argument must be a table."
app.store = table2array(app.UITable.Data);

I don't see a question.
Apparently app.UITable.Data isn't a table. This can happen when the data are from the same class. In that case, you don't need table2array(). For example,
uif = uifigure();
uit = uitable(uif,'Data',magic(9)); % all numeric
>> uit.Data
ans =
47 58 69 80 1 12 23 34 45
57 68 79 9 11 22 33 44 46
67 78 8 10 21 32 43 54 56
77 7 18 20 31 42 53 55 66
6 17 19 30 41 52 63 65 76
16 27 29 40 51 62 64 75 5
26 28 39 50 61 72 74 4 15
36 38 49 60 71 73 3 14 25
37 48 59 70 81 2 13 24 35
uit2 = uitable(uif,'Data',string(magic(9))); % all strings
>> uit2.Data
ans =
9×9 string array
"47" "58" "69" "80" "1" "12" "23" "34" "45"
"57" "68" "79" "9" "11" "22" "33" "44" "46"
