plugin issue

[john.mtchl]

i recently downloaded the new update (2020.11) and as soon as i did i went to work on a new song, mixed it , got tired took a break. came back few hours later decided to work on a project i started last week, but i cant open my plugins. i just click them and nothing happens, so i make a new project bring the old tracks over, add plugin to the fx rack and again wont open. i then try all my projects and the only plugins i can open are the ones that were already open when i opened the project. very confused, i changed nothing other than updating that im aware of.

Do you have another DAW or plug-in host you can try to load a VST into and see if the UI opens?  This would rule out a system wide problem.

I have not encountered this issue with the 2020.11 Cakewalk by Bandlab update (or with any Cakewalk by Bandlab update for that matter)

One thing you might want to try is updating your 2019 Vdist Runtimes.  (Reboot after installation)

i udated and restarted linked above, i do not have another DAW to open my plugins in, they do open in certain projects. but only if the plugin is already open when i open the project, and can close and open them in that project, i am not saying its a 2020.11 problem, it just happened after the update.
