Client crashes with "Deadlock detected" popup message

Had 4 separate occurences of a PoE Steam client crash with the popup error dialog saying "Deadlock detected" in the last 48 hours. Two of these were in maps, two were in hideout, shortly after having returned from a map.

The following error message appeared in the LatestClient.log each time:
2026/03/25 18:04:04 437634484 88f7e96b [CRIT Client 5896] Deadlock detected with timeout 10000ms; no running graph

It also seems to cause all shaders to be discarded, as many monsters and effects fail to render for a while upon restarting the game until shaders are computed again.

Steam client version 3.28.0d, running on PC. Couldn't supply a bug report reference ID due to the nature of the bug (client crash).

Same. These deadlock errors killed my GPU...
