Misbehaving project, is it windows?

[getho]

audio waveforms disappear or render incorrectly
thumbnails are greyed out, or slowly regenerate each time I enter a bin 

I have done the usual practices to appease the premiere gods. Cache, plugins cache, reboot, restart, disabled plugins, created a new project and imported this one into it.  This just after spending a couple of days editing the same footage in another project with no issues.  In the meantime, bloody windows updated.  

Anyone else having post updates problems?
this was the update:KB5029263

I'm on windows 11 22H2

Try resetting the preferences:

If that doesn't work, try resetting the Workspaces:
Reset a workspace
Reset the current workspace to return to its original, saved layout of panels.
1. Do one of the following:
• Click the Workspace menu icon and select Reset to Saved Layout.
• Choose Window > Workspace > Reset to Saved Layout.

If that doesn't work, try Preferences > Audio Hardware and set Input to None.

thank you, I must admit I didn't reset the prefs.  (but yes did the workspace stuff) And thanks for the audio hardware tip, that's a new one for me 🙂
