Thanks for this report. This seems to only reproduce on windows. The filename we get following those STR is "Screenshot 2022-08-10 at 10-03-42 Jiusion 2K HD 2560x1440P USB Digital Microscope for Android Cellphone and Tablet Windows Mac Linux 40X to 1000X Magnification Endoscope Handheld Mini Magnifier Camera for Coin Facial Skin Scalp Amazon.com.au.png" which seems to be bypassing the filename truncation we normally do to create a saveable file on all platforms.

That seems not to be the case. We take measures to ensure the filename isn't more than 255 bytes, and that filename doesn't exceed the limit. However, its possible might still be running into pathname length limits once this filename is joined with the download directory path. Or, this isn't a filename/pathname length issue at all.
