V1.7.1 Huge log files (100MB+) full of repeated errors on Mac - AGAIN in macOS 27.2

The following bug is back again, this time in macOS 27.2 and Topaz Video 1.7.1 -

V1.7 Huge log files (100MB+) full of repeated errors on Mac

In version 1.7, just opening some source files which worked fine in previous version create the following repeated error in the log, resulting in huge log files of hundreds of MBytes and severe delay in opening the file (e.g. 1 min + ). Once loaded, the file processes without issue. MacOS version is 26.6.1 MKV files created by MakeMKV is one example of when this issue occurs. 2026-08-12 23-13-55.541 Thread: 0x170ec3000 Critical Error sending packet to decode Invalid argument Failed setup for…

I tried exactly the same file with 1.7.1 and macOS 26.7.1 - EDIT: AND macOS 27.0.1 and the problem does not occur.

After further testing, I’ve discovered that although this problem happens on my Studio M3 Ultra on macOS 27.2, it doesn’t happen on my Studio M1 Max also on 27.2. It was the same test file (mpeg2 MKV) and same Topaz Video version (1.7.1).

Just a reminder that the problem doesn’t occur at all on macOS 27.0.1.

Thanks.

OS / TV version	1.6.1	1.7	1.7.1
26.7.1	OK	ERROR	OK
27.2	OK	ERROR	ERROR

Mac Studio M3 Ultra in all cases.

After testing with older app versions and reinstalling the latest again, the problem is now resolved.

Thanks.
