App pool is crashing and resulting in all sessions timeout

We are seeing strange thing -- when one person times out, everyone receives the time out. What that means is the application pool or WSL5 agent is crashing. However, we are having trouble figuring out why -- other than that it seems the more traffic we have on the site, the more frequent this happens. We are on .Net Framework 4.7.2 and using IIS 10.

Error in the event viewer:

Faulting application name: w3wp.exe, version: 10.0.14393.0, time stamp: 0x57899b8a Faulting module name: wslisapi5.dll, version:, time stamp: 0x5c36077b Exception code: 0xc0000409 Fault offset: 0x0000000000101dfc Faulting process id: 0x1718 Faulting application start time: 0x01d5ddb2cd93f78d Faulting application path: c:\windows\system32\inetsrv\w3wp.exe Faulting module path: D:\WSL5\wslisapi5.dll Report Id: ae76eb04-cbea-481a-9e57-ec85c00be929 Faulting package full name: Faulting package-relative application ID:
