Hi @rijnhardtkotze, thank you for your report.
We effectively identified an issue when adding or editing a new connection to SonarCloud with version 8.5 of SonarLint, as explained in this thread. We will work on providing a patch as soon as possible.
In the meantime, and if that’s a blocker, we invite you to downgrade to the previous 8.4 version by following the steps to directly install the plugin from disk while we work on resolving the issues.
