Same problem here!
Also after installing the announced KB5001567 patch printer still prints blank labels. No BSOD here.
Going back to Dymo Label Software 8.5.4 fix the problem by printing from this software but labels from software using .NET prints corrupted or missing barcodes (Dymo announces in 2015 there would be a bug in .net XPS printing, see Barcode Printing Issues » DYMO Developer SDK Support Blog.
This problem caused me to buy a newer model of Dymo since my one is deprecated and the SDK 8.X has changed to Dymo Connect. Now none of them work properly. I feel screwed.
