This solution worked for me: https://serverfault.com/questions/758919/rdp-crashes-after-entering-password
The cause was a bluetooth driver I installed aeons ago called "CSR Harmony Wireless Software Stack". Renaming the one file as described in the link worked, but I uninstalled the entire package as I didn't need it anymore.
Just for safety, the steps from the link:
"The simple fix is to head to
C:\Program Files\CSR\CSR Harmony Wireless Software Stack
and change
BLEtokenCredentialProvider.dll
to
BLEtokenCredentialProvider.dll.BAK
And the issue is now fixed for me."
