While looking at some recent test results, I noticed a lot of com.apple.WebKit.Networking.Development crashes in the "other crashes" section here:
https://build.webkit.org/results/Apple-Catalina-Release-WK2-Tests/r275172%20(1369)/results.html

Based on result history, I think these started after https://trac.webkit.org/changeset/275172/webkit landed

Exception Codes:       0x0000000000000000, 0x0000000000000000
Exception Note:        EXC_CORPSE_NOTIFY

Termination Reason:    Namespace <0x1F>, Code 0x2

Application Specific Information:
dyld: in dlopen_preflight()
