Performance issue on software upgrade

I have an RB4b with 4GB of RAM and I’m currently using a ORAM from September 2024 with just a WaveShare 3.5 Screen and Scarlet Solo by USB. I tried updating to the latest version and clearly noticed a drop in performance. The processor had higher usage, which caused sound crashes — something that didn’t happen with the older version. Does that make sense? Did I do something wrong?
