Recording long (a 40+ seconds) item in Playtime triggers this error:

I'm using Reaper version 7.22 (portable install, Windows 10) with a USB audio interface (Spark 2 with its ASIO driver set to 'safe mode'). I have 1 VST running (Midi drums) + 2 looped recordings (bass +rhythm). I'm adding a self-indulgent and not very good guitar solo, I get to the bit where I'm on my knees and nothing else exists in the world when this error happens.

I recently updated to Playtime 2.16.10 (yesterday). I've not seen this error before (I was using version 2.16.4 prior to this)

I see there's an existing closed issue referring to a similar error but the info on that suggests it's triggered by high sample rates - I'm recording 44kHz mono, 24bit

Hi. To which directory do you record the files? I suppose you have saved a project before recording, so it will probably record directly to the project directory. Is that directory on a somewhat slow disk maybe? Just asking to get more context. It's definitely a bug.

the files go to a 1TB NVME SSD, which is about half full - I don't think the disk is likely to be the issue (but with Windows you can never be sure). My box is generally in pretty good health.

I doubled the ASIO driver buffer size and had another crack at it yesterday and it didn't crash. I guess it's possible that this is just an ASIO buffer under-run (or whatever it's called) but the error report makes it look like something breaking in the Playtime stack? I dunno :)
