I ran top, and noticed that it quickly ate up all the system memory and swap with HDR enabled (32Gb ram and 16Gb swap)
The log confirms that system memory is the problem, but unfortunately doesn't give any reason. Could you please check if the issue is related to CSMT, or if it also occurs without using experimental features. You can temporarily disable it in the winecfg Staging tab.
