I upgraded VW2019 to SP5.3 recently, and now the program hangs a lot.  It doesn't completely crash, but I get the spinning wheel repeatedly, and things slow to such a crawl it might as well have crashed.  Waiting it out until it catches up to last couple of inputs takes too long - better to just force quit, lose the work and try again.   Can someone tell me how to revert back to 5.2, or even 5.1.  This didn't happen with those service packs.   Are there any more updates comin
