Step-by-step instructions, in case, someone else has the same issue:

1.: yum history list to get the transaction id of the last update.

2.: yum history info # with # being the id from step 1, to list the updates done in this transaction. The interesting part for me was

Updated microcode_ctl-2:2.1-26.xs26.2.xcpng8.2.x86_64  
Update                2:2.1-26.xs28.1.xcpng8.2.x86_64

3.:yum downgrade microcode_ctl-2:2.1-26.xs26.2.xcpng8.2.x86_64 to downgrade to the previous version. You will have to enter the older version for this command.

4.: Wait until it's done, reboot, test, pray it'll work again.

This is just a workaround! Microcode updates are important security and/or functional updates. Downgrading can lead to security issues.

Thanks for sharing the resolution, im sure it will help someone else in the future.

nikade Here I am!
Same problem (obviously) for Intel J4005 (I'm new to xcp-ng and I'm thinking about a homelab migration from Proxmox to an old NUC 7 as a test).
So thank you all very much for clarifying me which of the 65 updates (from the initial downloaded image) was the problem that was driving me crazy in these days of testing!
