Hi @a.radder , sorry you’re having problems with Play. Although your problem might be different root cause, after analysing this report we figured out it is exactly the same issue as Freeze whilst loading sample packs, folders or files which exceed 32 char The fix should be included in the next update. I am attaching older firmware if you want to try it out: PolyendPlay_v1.4.1.zip (1.1 MB) Please backup your project before you continue so you always have a copy of it safe. Finally, there are some workarounds mentioned in the other bug report I shared, you can try those also, but please remember to backup before also 
Thanks for your message and patience while waiting for a fix
