Evolution not working with MS Exchange (F34 Silverblue)

Hi. There is an issue somewhat similar to mine (Cannot configure evolution with Exchange), but I believe is not the same. I’m running Fedora 34 Silverblue and use Evolution to connect to my university’s MS Exchange server. With F33 regular it worked quite well. At first, with F34 Silverblue it also worked well, but then Evolution started failing, with a “Source ‘[my email address’] doesn’t support prompt for credentials”. This account is configured via settings’ online accounts. Oddly, email works by configuring it in Evolution, but not calendar nor contacts. The version of Evolution installed is from rpm. I filed a bug report, with no response so far. Any ideas? Thanks in advance.
