This is a known 4.9 bug (2nd extruder over retraction). Expect a 4.9.1 release soon.

I am using Cura 4.9.1 with my Sovol SV01 printer. I found out that my retraction is getting longer and longer over a print. Instead of 3mm i get retractions of up to 10mm and more, increasing over the length of the print. As a result my printer starts clogging. Is that a known bug?

I haven't heard of that one. Post a gcode file here that has the problem. Somebody will take a look.

I had problems on Cura 4.9 with material retract on extruder 2. It seemed that the material was retracting on extruder change but was not going back ready to print. Going back to Cura 4.8 rectified the problem.
