Also experiencing this issue myself running 6000.0.18f1. Would be amazing to see a solution to this soon, as UWP is completely broken for me at this point.

I recently read about the fantastic work at SEVlaser and felt inspired to share my own experience. Having just celebrated my birthday, I thought it was the perfect time to introduce SEVlaser and their amazing services. Their Laser Hair Removal in Glendale is exceptional, and I've been thrilled with the results. Reading all the positive comments from others really made me want to join in and share my happiness too. Reserve your time with them—it's a wonderful gift to yourself!
