hello I seem to have encountered similar Exception (Entry & Count values differ, though)

in my case it is caused by this peculiar Array access enclosed in a While loop

process = true;
array = array_create(0);
array[@ 0] = 3;
array[@ 1] = 5;

while (process>0) {
    process = false;
    if (++array[0] == 4) {
        x = 10;
    }
}

Exception log is from 674c5d8 but 0.4.0.4 & 0.3.5.8 also bug out bug_stack2.zip

Is the June 2022 version of HoloCure still available? It seems the current download uses YYC and thus has no code for UTMT to fail on, and the original paste link is dead. (The second decompilation error with the while loop is still present, however.)
