I reached out to support. They just emailed me back with a corrupted shared password. I removed it and tried to log in again. At first, I saw the spinning safe but then I cleared the cache and it immediately logged me in.
Brilliant. Thank you!
I'be been trying to get them to figure out a corrupted password for months, so I could see if this solution works.
No Joy. They are not responsive to solving. Do you know how we can find these without waiting on them?
Not solved. I understand the theory of this solution, but how do we implement it if we cannot find the corrupt passwords? And if support is no longer working?
If they are no longer doing support, what does one do to even test this solution?
\I managed to contact them via https://support.lastpass.com/s/contact-us?language=en_US . I called them and they said they would get back to me and actually did. They emailed me with a link to the corrupt shared password.
I had the same issue and opened a support case through https://support.lastpass.com/s/createrecord/Create_Case asking to specifically look for a corrupted shared password. They responded within a few hours saying I was right to request this and told me they had found one. But, after I deleted it, the issue was still there.
I then asked to check again and, lo and behold, there appeared to be another corrupted shared password. Deleting that one too, resolved the issue. Yay.
They also mentioned that they are working on a fix...
I had tried a number of things listed, but what worked for me and has stayed working for over a week now, was to delete the Lastpass Mac App, follow below to reset my account, reload my passwords, re-install the App- https://support.lastpass.com/s/document-item?language=en_US&bundleId=lastpass&topicId=LastPass/reset...
Basically you delete app, export your passwords, reset your account and import your passwords, re-install app.
Safari and the Mac Lastpass app have been working fine since.
