I cannot use the Kindle App on my iMac, which I recently upgraded to Big Sur. It runs just fine on my Macbook (both under Windows 10 and OS X Catalina), and on my iPhone. The behavior is this: when I open a book, it takes me to my current location and about five seconds later it crashes with this message: Kindle quit unexpectedly (well, maybe THEY didn't expect it, but I've come to expect it!) and a crash dump that they promise to send to Apple support. I have followed the instructions found here:

but to no avail. Any other help would be appreciated
