On Windows 10, I had LV 2020 SP1 32-bit working fine

I installed the f1 patch using NIPM

Then this :

I noticed because these VIs are use by the File Checksum VI

It's not too difficult to fix, see this video I made :

For me this sounds like a typical "ObjectCache" problem. For patches from NI it is always recommended to clear the LabVIEW ObjectCache.
C:\Program Files (x86)\National Instruments\LabVIEW 20xx\VIObjCache

- Close LabVIEW
- Delete all files in this directory.

A CAR already existed : 1103060

R&D is planning to fix it in LV 2022.
Recommended work-around is a mass compile after installing any new version / patch.
