Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1050/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 431.07
Broken: version: 2.92.0, branch: master, commit date: 2021-02-24 16:25, hash: rB02948a2cab44
Worked: (newest version of Blender that worked as expected)
Short description of error
I can no longer use LMB-hold to initiate a box-select in the 3D editor in either object or edit mode. I can use LMB-hold to initiate a box-select in the UV editor. I can initiate box select in 3D editor with the hotkey "B". Coincident with the box select issue arising, now, when I select an object with a direct LMB-click on an object in 3D editor the active tool is "Move", as if the Move tool is always selected (which it's not). I select an object with LMB-click, release, hold LMB, move my mouse and the selected object moves. The Move dialog box appears at the lower left. This "Move" happens even though the select box tool is highlighted, not "Move". My selection cursor is set to "Box".
Very strange. This all started today, after I installed (and subsequently removed) an add-on ("weld seam"). I uninstalled and reinstalled Blender and the problem persists. I used a registry cleaner and the problem persists. I uninstalled Blender, cleaned the registry, reverted to an old system restore point (when everything worked), reinstalled Blender, and once-again, same problem persists. I can't use LMB-hold to select anything in the 3D Editor.
