Internet Explorer version shuts down my productivity tool

Hi there,

We are a company having developed a Productivity Assesment tool for our own employees. We are facing a problem with Internet Explorer version 11.492

Issue:
When I use this tool on Internet Explorer (IE) version 11.492, the tool gets <g class="gr_ gr_24 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del" data-gr-id="24" id="24">shutdown</g>.

Observation: 
There may be a security feature that might be present in this version of the IE that is hindering my tool.

Other than this version of the IE, my tool functions normally with other versions of IE along with other Web browsers.

Request: 
- We would like to know how to get around this <g class="gr_ gr_32 gr-alert gr_gramm gr_inline_cards gr_run_anim Punctuation only-del replaceWithoutSep" data-gr-id="32" id="32">issue,</g> so that my tools <g class="gr_ gr_31 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar multiReplace" data-gr-id="31" id="31">works</g> well with IE 11.492

- Which <g class="gr_ gr_25 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" data-gr-id="25" id="25">patchfile</g> should we add to our tool? Or how can we customize it?

We appreciate your help!

Thanks
