High CPU usage for Windows Error Reporting Service on Windows 10

I recently upgraded to Windows 10 Version 2004, via the Slow Ring of the Windows Insiders programme. About a day later, I noticed that my computer is significantly slowed down and things like right-clicking on folders (but not files) takes a very long time. I checked the running processes and sure enough, the Windows Error Reporting Service was frequently consuming between 30-100% of my CPU:

What is this issue caused by, and how can I fix it?

Based on the little I've been able to find on this I'm assuming that this is a fairly new bug exclusive to Insiders, and with error reporting not being particularly useful for the day-to-day operation of my system I decided the best way to deal with it would be to disable the Error Reporting Service until the bug has been resolved.

Lifewire offers a detailed tutorial to do so for anyone with little technical experience, but for everyone else, a more concise version is:

1. Open services.msc from the search bar

2. Search for the Windows Error Reporting Service" and double-click it

3. Change its startup type to Disabled, and apply the changes

EDIT: Although this solution fixes the high CPU usage, the very slow right-click on folders is still present, so it seems that this is a separate bug.
