It seems related to bitcoin-core/qa-assets#155.

Yes, the issue is known and will be fixed next week. To help with progress, review on #28697 would be helpful.

I'm sorry, but I can't see how #28697 can resolve this issue as it itself fails with the same timeout.

It doesn't fix the issue. It helps with making progress on fixing the issue.

The basic problem is that over time fuzz inputs are added, leading to longer time requirements. Thus, they will need to be removed occasionally. However, they currently can not be removed with the vanilla script in the master branch of this repo, because the script runs into a memory limit and crashes.

See https://github.com/bitcoin-core/qa-assets#pruning-inputs for more info.
