Business account not syncing after update, even after re-linking

Wish I had not updated - had my personal and business accounts linked prior to the recent version. Now the business account will not sync, even after I removed the files and relinked the account… I thought it was due to disk space (I have almost 200 GB in that account), but even clearing extra space so everything could redownload it still is stuck “processing files” (and there’s no way I can make that much free space on my laptop, so hopefully redownloading the whole account is not necessary as a fix).

My last resort will be to remove all the files via the web interface and then relink the account and reupload the files. May take a while...
