[GPU PLM] Editor stalls on closing with various RIF errors after ungraceful fallback to CPU PLM when baking with Radeon denoiser

Progressive Lightmapper


Steps to repro:
1. Pull Enter The Room project ( and sync to revision a9e374d93cbc2937a50070149fdcabf91eae130d;
2. Open scene 'Sequence 4 One Year Ago-Mixed';
3. In the Lighting window Direct and Indirect Denoiser to Radeon Pro;
4. In the Lighting window enable autobake and let it finish;
5. When the baking completes, in the Hierarchy select Furniture gameobject;
6. Disable Furniture gameobject;
7. Let the automatic GI baking finish;
8. When the baking is completed, enable the Furniture gameobject again (or toggle-untoggle it several times with the interval of several seconds);
9. Attempt to close the Editor.

Expected result:
Editor is closed. GPU baking is smooth, no fallback to CPU PLM and no errors are thrown.

Actual result:
Editor stalls on closing.
