IIS app pool crashing with exception 0xc0020001 in IIS 10

Question

My app pool keeps crashing. From past 4 weeks it was crashed around 8 times. I'm not sure where to even begin to troubleshoot the issue.

I have checked the code if there is any exception occurred from the code but didn't found anything. May be I have framework 4.0 and on server it is 4.7 so may be it conflict?

I used Event Viewer to get the following information:
