Since OP didn't bother to mention how to fix this issue, navigate to the file in OpenIV and use Ctrl + F to find "990" and change the value to 1900 or higher as needed. In my particular case, the exact line below was the cause of this crash.
<PoolName>ScriptStore</PoolName>
<PoolSize value="990"/>
Change 990 to 1900 and it should hopefully work.
