musescore 4.4.3 on an imac

Since I started using the newest version of Musescore (4.4.3) my home internet has repeatedly crashed over the last month nearly every time I tried to upload a score. For example, I started an upload of a simple test score with just one measure and four notes and the upload slowly began and after a minute or so the entire home internet crashed. I had no issue of restarting my internet but it crashed again when I retried the same upload again. I have an iMac, Ventura with lots of free memory and storage. I do not have this issue with uploading to Youtube. I did multiple restarts of my computer, switched browsers and, did troubleshooting with my internet provider and Apple to no avail. Finally, I switched back to Musescore 4.3 and so far, the last couple of days, have not had a problem with uploads.
