I’ve posted a screen concerning crash on REAPER 6.71 (Windows 10 platform):
HERE – bottom.
Perhaps the error message is identical. Bitwig Studio 4.4.3 doesn’t show the error message, but VCV Rack 2 as CLAP plugin isn’t visible / disabled.
Other CLAP plugins on my rig (Vital, Odin2, Surge XT / XT Effects, Dexed 0.9.3 Nightly beta, u-he Diva 13510 preview demo, Filterjam, TAL Reverb 4) seems to work fine on both REAPER 6.71 and Bitwig 4.4.3.
