UI stopped working on RPi4 buster on master branch

Hello, after updating zynthian on RPi4 today, UI does not come up after reboot. Manually reverting zynthian-ui to a56f74b, it is working again. I did not have time to investigate the logs yet.

I just update and it works for me. Please, if updating again don’t solve the problem, try reburning+update or send the logs.

This has probably something to do with Pianoteq. I updated zynthian-ui to HEAD on master branch and now the UI starts, but I can not add Pianoteq layer. The UI Log says:

Oct 29 17:10:12 zynthian startx[434]: ERROR:root:Can't add layer Pianoteq 6.6 STAGE => 'Celtic Harp'

Ok, running “Update Presets” on Software->Pianoteq page through Web UI fixed the problem. Shouldnt be this step running automatically on every update when Pianoteq is present?

I will solve the problem ASAP.
