I'm facing the same issue on build 1712795774, Arch Linux.
Steps for reproducing this issue:
This issue only happen when a custom compatibility tool is present in XDG_DATA_HOME/Steam/compatibilitytools.d.
Also happening on build 1713317598, Arch Linux.
Reverting to build 1709846872 corrects issue.
Can confirm I had the exact same issue, though it was just the normal Steam Beta Client; rolling back to the normal stable track resolved it.
Thank you, this will be fixed in next Steam beta update.
