I've updated Premiere Pro to 23.1. today, and now it stops finding the file, and when I locate it and try to import it back into my project I get a generic error message.
Glad to hear from you, and thanks for the post. I can see how this might be hard to deal with. Over the past year, I've seen this issue rise and fall in severity. I'm not sure why it happens. It could be the same place others are receiving these files. Sorry about that. One quick question, where did you get the file?
A workaround might help. Try replacing the clip with uncompressed .aif or .wav source files. If you do not have access to the source files and are forced to use a .mp3, try changing the extension for the source file to ".wav." Then, reconnect the file. Let us know if it worked.
