Sentinel 1 processing not possible - no error

Unfortunately i don’t get past 66% or 100% after processing one file in following graph


This graph can be executed on a much slower PC. No error is thrown when executing this graph on the current PC.
Can anybody explain this behaviour? It seems to be just Sentinel 1 data, Sentinel 2 graph processing is possible.

Updates are installed on both machines?

Yes, both have been updated with all toolboxes available

Do the required orbit files and DEM tiles download and get stored normally?

ps. it is probably inefficient to put terrain correction and radiometric terrain flattening in the same graph.

They don’t, i downloaded them manually and put them into the aux data.

It still processes the graph with a batch size of 105 on my weaker PC. And i copied everything the exact same way to my stronger PC
