I have the same problem. The nvidia drivers (version 470 in my case) don't load after upgrading to 5.13.0-41-generic. Reverting to 5.13.0-39-generic fixes the problem.
I did notice that -41 has a lot of changes from the "stable" impish kernel and that the modules loaded on my machine with -41 include lots of wmi and i915 stuff: i915 2400256 1 i2c_algo_bit 16384 1 i915 drm_kms_helper 253952 1 i915 cec 53248 2 drm_kms_helper,i915 drm 557056 3 drm_kms_helper,i915 video 53248 2 dell_wmi,i915 wmi 32768 5 dell_wmi_sysman,dell_wmi,wmi_bmof,dell_smbios,dell_wmi_descriptor which the -39 modules does not load. Black listing these modules does not fix the problem. The 2 machines we are having issues with are Dell Optiplex 7090 with a Nvidia GeForce RTX 3070 so I tried the 5.14.0-1038-oem kernel which fortunately fixes the problem for me.
