I have just created a Manjaro 19 virtual machine (hosted on fedora 31) and installed thunderbird. As I've done for many other VMs, I copied my .thunderbird directory from fedora 31 to my home directory on Manjaro. However, it errored out with the "you've tried to open a profile from an older version of thunderbird..." Both Manjaro 19 and fedora 31 are using thunderbird version 68.5.0. I've tried several different ways including using profile manager with no success. When I run thunderbird from the command line, I get these error messages: JavaScript error: resource://gre/modules/XULStore.jsm, line 66: Error: Can't find profile directory. ###!!! [Child][RunMessage] Error: Channel closing: too late to send/recv, messages will be lost JavaScript error: resource://gre/modules/AsyncShutdown.jsm, line 694: Error: Phase "xpcom-will-shutdown" is finished, it is too late to register completion condition "UserInteractionTimer 1 for document 7fbeccc6c000" JavaScript error: resource://gre/modules/XULStore.jsm, line 66: Error: Can't find profile directory. ###!!!

Does anyone have any ideas I might try?
