Ardour 3.2 freezes when loading old sessions

hi all. I am trying to load sessions from ardour 2 and ardour 3.2 freezes when loading it (just the splash screen, and the message ‘Please wait while ardour loads your session’. My xml from the sessions reads like this:

<?xml version="1.0" encoding="UTF-8"?> <Session version="2.0.0" name="bkk sounds" sample-rate="48000" id-counter="2309"> ...

i make sure to start jack with a sample rate of 48000 hz. I also started ardour with flags --debug all and the last lines read like this:

PBD::DEBUG::AbstractUI: Ardour/140131692722624 direct dispatch of call slot via functor @ 0x7fff29c58fb0, invalidation 0 PBD::DEBUG::AbstractUI: Ardour/140131692722624 direct dispatch of call slot via functor @ 0x7fff29c59090, invalidation 0 PBD::DEBUG::AbstractUI: Ardour/140131692722624 direct dispatch of call slot via functor @ 0x7fff29c58cf0, invalidation 0 DEBUG::ProcessThreads: 140130746517248 signals 0 DEBUG::ProcessThreads: 140130746517248 goes to sleep DEBUG::ProcessThreads: 140130745988864 signals 0 DEBUG::ProcessThreads: 140130745988864 goes to sleep

I also happened to run once onto a window which read that ardour was copying the old session to a new name with a ‘-2000’ appended, but the copy was never performed.

I’ve tried to load different sessions and they all freeze.

any idea?
