In general it seems like more tabs open in Duplicati is more prone to having odd behavior.
When I was testing with just one, GUI was less flaky. Recently I’ve had more than normal.

If all tabs are using the same refresh token, there could be some kind of race where multiple tabs request a new access token, using the same refresh token. In most cases this would cause the anti-token-theft to trigger and log you out.

I think I have an idea for why this is happening then, but I not sure what the solution would be though. Thanks for the detailed debugging.

Unfortunately, new ZIP code in 2.0.9.108 chokes, so you might need a 2.0.9.107 .zip install.

It is using the built-in .NET zip library in 2.0.9.108 by default.
You can set --zip-compression-library=SharpCompress to select SharpCompress.

IMO the decompressor code will be nearly impossible to fix without a better problem reproducer, meaning please help with your two or three suspect files. Opening an issue on third party library GitHub - adamhathcock/sharpcompress: SharpCompress is a fully managed C# library to deal with many compression types and formats. will probably go nowhere (for good reason) as simply an oddity that shows up in Duplicati every 6 years. Unless the problem is in Duplicati use, your trouble-causing files are probably the key, but we’d have to find which one causes problem, then ideally isolate it to a single Duplicati block (one of the files with the block hash as its name).

If the data is not confidential, and the decompress error is reproducible, I would be able to debug some further if you can share the file. I think a major reason that we have not seen this more often is that it is specific to the LZMA (de-)compressor which is not commonly used.
