YAC blocking MacBook Pro macOS Catalina 10.15.4

hi Luis,
yac reader library is locking MacBook Pro from waking up and gives kernel panic error. computer restarts each time. I have an external ssd disk with library dat and also use the library as a server with iPad. any suggestions? thanks

If you run it without the ssd does it happen the same?

no it didn't, so after hours of trial and error, I came to the conclusion that it was ssd itself. Erased, reformatted as MacOS extended instead of ExFat, reload the whole library and so far it works in the last 24 hours w/o any glitch. thanks again for response. I ll update if I witness changes

Hmmm, I need to do some tests with ExFat and see if it can cause problems...

Thanks for sharing your findings.
