Start by reproducing the render failure while scrolling an HTTP request folder and searching in Insomnia 8.6.1 on Windows. Use the reported app.asar/index-db9674c5.js stack trace to locate the null value involved in reading index, then verify that scrolling and searching no longer produce the render failure.
