Sudden High CPU Load and RAM-Usage

Hi,
we use an older Version (14.0.11) of RDM and from yesterday to today we had the Issue, that on Startup on all machines the application takes between 80% and 100% of CPU and allocates up to 22 GB of RAM (if the machine it runs on has enough). After a time a popup appears asking if a script should be executed further. If this is answered with no, RDM can be used but very slow and laggy, the high RAM consuptions stays. The issue didnt appear on machines without internet connection. This led us to blocking some IPs RDM tries to connect to on startup, which resolved the issue.
My guess is, something got changed on the Backend RDM connects to for update checking or something else which leads to a kind of loop in our Version.

Would be nice if this could be undone, so we wouldnt have to block the IPs further.

Best Regards,
