EXACTLY my issue. Mine just freezes whenever I respring anywhere. Really weird.I came across a similar problem last night. Whenever I respring from SBSetting, it freezes.
All this started happening after I installed RemoveBackground so, I removed it and decided to do a clean restore. The problem was gone until I re-installed BiteSMS, it started happening again.
I just tried changing my theme in WB and when I hit respring, nothing happens.
