Yea, OS version is version 1903 (10.0.18362). I think it will fix it, but Trezor need to update their bridge to use the libusb fixes.

Good afternoon @cculianu,

I just received another crash report related to this issue. The crash occured on Electron Cash 4.2.5. I’m not sure which versions of Electron Cash include the fix but this is the first report from anything newer than 4.2.0 since you closed the issue.

Could you please check if this issue really is resolved? Here is the traceback that I just collected:
