Cura 4.7.1 was running fine. I installed Cura 4.8 and 4.8 loaded and ran VERY slow. More than 5 minutes to load the software. Loading model files, rotating objects, etc. were painfully slow. I tried 4.7.1 again and it now has the same issues. I uninstalled 4.8 and 4.7.1 and re-installed 4.7.1 and it still runs painfully slow. I ran Creality Slicer, which is based on a Cura engine and it runs fine. How can I get Cura 4.7, 4.8, or any other version running again on my Windows 10 desktop?
