For those of you still having this problem, here is how I fixed this. You need to change the metadata for the font to match the filename of the font. The spelling must be exact in the plist file, font file, view font name. If your system cannot find the file you will need to click on the font name, go to the identity and type tab on the top right settings window. click on the full path and select your font file name. This will set your project to exactly where the font file is located. If this doesn't fix the error then clean your build folder or issues and recompile. I have been looking for a solution for this for a long time. If this works for you, please mark this reply as the accepted answer. Thanks, DB

For now this is an ios16 problem. Make your maps "flat" and not "realistic" and your application will stop freezing or crashing.
